Net runtime error 1026

Question

Issue: How to fix .NET Runtime Error 1026 in Windows?

Hello.  I wanted to open an application on my Windows PC but it does not open or crash shortly after launching. I also receive a .NET runtime error 1026. I have no idea what could be causing the issue. Does anyone have any ideas?

Solved Answer

Sometimes, while trying to open an application on their computer, users may encounter frequent crashes. Some are completely unable to launch apps. A lot of the time users open Event Viewer in Windows and find multiple .NET Runtime Error 1026 errors in quick succession. It may also display an error message:

.NET runtime error 1026 bearing the following description under Event Viewer – The process was terminated due to an unhandled exception. Exception code c00000fd.

Most users report that whenever a new event of this kind is created, they also end up seeing an app error pop up. It was confirmed that the issue occurs on Windows 7, Windows 8.1, and Windows 10 most likely due to some kind of conflict between two 3rd party programs or between a 3rd party program and a native Windows process.

Most often, the .NET Runtime Error 1026 indicates that Windows is missing some files to be able to smoothly run a program. When an error code such as this appears, Windows cannot start apps. Other common reasons may include incorrect user input and accidentally deleted files from the registry^[1] that now cause system malfunctions.

Troubleshooting manually could take a while because it is unclear what is causing the issue, so you can try using an automatic solution ReimageMac Washing Machine X9 to avoid going through all of the possibilities. The repair tool can identify the damaged system components, fix BSODs,^[2] and registry issues by scanning the system. This software could also be used to free up space by clearing cookies and cache,^[3] which should boost the device’s performance.

Below you will find a few manual methods that could fix .NET Runtime Error 1026 and let you open applications with no trouble again. Note that this will take a while, so please follow all of the steps very carefully:

Solution 1. Clean Boot

Clean boot is one of the troubleshooting techniques that help identify if an app is causing the issue. It is usually performed when non-Microsoft products cause software conflicts. A clean boot helps in the easy start-up of OS by only loading essential files and programs:

• Press Windows + R, type msconfig, and hit Enter
• Go to Services tab and tick the Hide all Microsoft services checkbox
• Select Disable all
• Go to Startup tab and click Open Task Manager

• Here, right-click on each of the non-Windows entries and select Disable
• Close down the Task Manager
• Go to Boot tab and tick the Safe boot option
• Click Apply, OK, and restart your computer
• If the issue is still there after this step, proceed further

Solution 2. Run SFC and DISM Scans

Use Command Prompt commands to repair system file corruption:

• Open Command Prompt as administrator
• Use the following command and press Enter:
  sfc /scannow

• Reboot your system
• If SFC returned an error, then use the following command lines, pressing Enter after each:
  DISM /Online /Cleanup-Image /CheckHealth
  DISM /Online /Cleanup-Image /ScanHealth
  DISM /Online /Cleanup-Image /RestoreHealth

Ensure that your disk is not damaged. You can perform checks using Administrative Command Prompt:

• If you are using an HDD as your main driver (where your operating system is installed – C: by default), use the following command and press Enter:
  chkdsk c: /f
• If you are using SSD, use this command:
  chkdsk c: /f /r /x
• If you receive an error, type in Y and hit Enter
• Restart your device to perform the check

Solution 3. Run the .NET Repair Tool

• Open your browser and access the Microsoft .NET Framework Repair tool download page
• Click on the Download button (under Microsoft .NET Framework Repair Tool)
• Check the NetFxRepairTool.exe box and uncheck everything else, click Next
• Double-click on the installation executable that you just downloaded, click Yes when prompted at the UAC (User Account Control)

• Follow the on-screen instructions and check the I have read and accepted the license terms box when prompted by the ToS before clicking on Next
• The utility should have already begun the scanning of the .NET dependencies installed on your computer, wait until the process is complete
• Click on Next to automatically apply the repair strategy that the utility recommends
• Click on Finish to complete the process and restart your PC

Solution 4. Disable and re-enable the .NET framework

• Type Turn Windows features on or off in the Windows search bar and press Enter
• When the Windows Features window opens, click on the + icon, adjacent to .NET Framework 4.7 Advance Services to expand its menu
• Uncheck all the options listed under it

• Uninstall the framework and restart your PC
• Reinstall the .NET Framework, go back to the Windows Features window, and click on the + icon, adjacent to .NET Framework 4.7 Advance Services
• Check all the options back and restart the computer again

Solution 5. Rename the Launchpad.exe file

• Start by ensuring that the user account you’re currently using is an administrator
• Navigate to the root directory of your OS drive (most likely C:/), right-click on the Users folder, and choose Properties
• Access the Security tab, select the Administrators group from the menu below, then click on Edit
• Inside the Permissions for Users window, select the Administrators tab and ensure that the Allow box associated with Full control is checked

• Click Apply to save the changes and ensure that you have Full Control permissions to the Users folder
• Return to File Explorer and access the View tab, check the Hidden Items box
• Use File Explorer to navigate to the following location:

C:\Users\[username]\AppData\Local\Microsoft_Corporation

• See if you can find an executable named Launchpad_XXX.exe (XXX is just a placeholder. In your case, you will see a random number of characters)
• If you can locate the executable, rename it to something different, or simply add the .old extension at the end of the name. This will force Windows to disregard this file and create a new healthy equivalent that will hopefully not create the same kind of issues
• Open Event Viewer and see if the problem is now fixed

Solution 6. Re-install Runtime Libraries

• Go to Programs and Features, find and highlight the Microsoft Visual C++ Redistributable Package
• Right-click it and choose the Uninstall option

• Reboot your computer

Solution 7. Reset every Windows Component

• Open Command Prompt as administrator again

• Copy and paste the following commands, pressing Enter after each:
  net stop bits
  net stop wuauserv
  net stop appidsvc
  net stop cryptsvc
  Del “%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*”
  rmdir %systemroot%\SoftwareDistribution /S /Q
  rmdir %systemroot%\system32\catroot2 /S /Q
  regsvr32.exe /s atl.dll
  regsvr32.exe /s urlmon.dll
  regsvr32.exe /s mshtml.dll
  netsh winsock reset
  netsh winsock reset proxy
  net start bits
  net start wuauserv
  net start appidsvc
  net start cryptsvc
• Restart your PC

Several Windows users have opened up Event Viewer and discovered a lot of .NET Runtime Error 1026 errors that are happening in quick succession. Most affected users are reporting that whenever a new event of this kind is created, they also end up seeing an application error pop-up. This issue is confirmed to occur on Windows 7, Windows 8.1, and Windows 10.

After investigating this issue, it turns out that there are several different underlying causes that might be producing the .NET Runtime Error 1026. Here’s a list of potential culprits that might cause this error:

Now that you know every scenario that might be the underlying cause of this issue, here’s a list of methods that other affected users have successfully used to get to the bottom of this issue:

Method 1: Clean Boot Procedure

According to most documented cases, this issue can most likely occur due to some kind of conflict between two 3rd party programs or between a 3rd party program and a native Windows process. This is way more likely if you’re only noticing new instances of the .NET Runtime Error 1026 error popping up when you attempt to open a 3rd party application.

If this scenario is applicable, you can isolate and identify the culprit by starting your computer into clean boot mode and seeing if the issue still occurs.

This operation will ensure that your computer boots up in a mode that disallows the running of any 3rd party service, process, or startup item.

If you boot your computer into a Clean Boot state and you see that the issue stops occurring, you can go ahead and systematically re-enable every process and startup item and do regular restarts until you manage to pinpoint the culprit.

In case the same .NET Runtime Error 1026 error is still occurring even after you boot your PC into the clean boot, move down to the next potential fix below.

Method 2: Running the .NET Repair Tool

If a clean boot didn’t work for you, our recommendation is to proceed with a series of troubleshooting steps that will allow you to fix any underlying issues with the .NET redist packages that are currently installed on your computer.

Several affected users that were also struggling with this issue have reported that they finally managed to prevent new instances of the .NET Runtime Error 1026 error from occurring by running the .NET Framework Repair Tool – This tool will automatically scan your computer and fix any .NET dependencies that might be creating issues.

If you haven’t tried running the .NET Repair tool, follow the instructions below for step by step instructions on doing so:

1. Open your browser and access the Microsoft .NET Framework Repair tool download page. Once you’re inside the page, click on the Download button (under Microsoft .NET Framework Repair Tool).
2. After you get to the next screen, start by checking the box associated with NetFxRepairTool.exe while unchecking everything else. Next, click on Next to advance to the next menu.
3. Once the download is complete, double-click on the installation executable that you’ve just downloaded, then click Yes when prompted at the UAC (User Account Control). 
4. After you manage to open the Microsoft .NET Framework Repair Tool, follow the on-screen instructions and check the box associated with I have read and accepted the license terms when prompted by the ToS before clicking on Next to move forward.
5. At this point, the utility should have already begun the scanning of the .NET dependencies installed on your computer. Wait patiently until the process is complete and avoid interrupting it to avoid additional issues.
6. Once the operation is finally complete, click on Next to automatically apply the repair strategy that the utility recommends.
7. Once the fix is successfully applied, click on Finish to complete the process. If you’re not prompted to restart automatically, do it yourself and see check Event Viewer once the nest startup is complete to see if the same kind of issue is still occurring.

If you already ran the .NET Framework Repair utility and you’re still seeing this kind of issue, move down to the next potential fix below.

Method 3: Renaming the Launchpad.exe (if applicable)

As it turns out, you can expect to see this error due to a new Windows Update that ended up breaking an existing Windows 10 functionality. Although the .NET Runtime Error 1026 error is not really indicative of this potential culprit, several affected users have confirmed that they were able to get Full Control permissions for the Users directory and renaming the Launchpad.exe to something different in order to prevent Windows from using it.

Note: If you have multiple users account on this computer, you need to do this for every user present inside the C:Users directory.

If you haven’t tried this method yet, follow the instructions below to obtain Full Control permissions in the Users directory and rename the main Launchpad executable:

Update: As far, this particular fix was only confirmed to work for Windows 10.

1. Start by ensuring that the user account you’re currently using is an administrator. 
2. Next, navigate to the root directory of your OS drive (most likely C:/), right-click on the Users folder, and choose Properties from the context menu that just appeared.
3. Once you’re inside the Properties screen, access the Security tab, select the Administrators group from the menu below, then click on Edit.

   Note: When prompted by the UAC (User Account Control Prompt), click Yes to grant administrative privileges.

4. Inside the Permissions for Users window, select the Administrators tab and ensure that the Allow box associated with Full control is checked.
5. Click Apply to save the changes and ensure that you have Full Control permissions to the Users folder.
6. Return to File Explorer and use the ribbon at the top to access the View tab. From the contextual menu that just appeared, check the box associated with Hidden Items.
   
7. Next, use File Explorer to navigate to the following location:

   C:Users[username]AppDataLocalMicrosoft_Corporation

8. Once you’re inside, see if you can spot an executable named Launchpad_XXX.exe
   Note: XXX is just a placeholder. In your case, you will see a random number of characters.
9. If you can locate the correct executable, simply rename it to something different or simply ad the .old extension at the end of the name. This will force Windows to disregard this file and create a new healthy equivalent that will hopefully not create the same kind of issue.
10. Open Event Viewer and see if the problem is now fixed.

If you’re still spotting new instances of the .NET Runtime Error 1026, move down to the next potential fix below.

Method 4: Reinstalling Windows Media Player

If you’re encountering this error while attempting to launch an application or game that needs to make use of a Windows Media Player dependency, you might be able to fix this issue by reinstalling the local installation of Windows Media Player.

Typically, you will be able to spot if this scenario is applicable by checking the Event ID log file. If it contains mentions of Microsoft.Xna.Framework.Media.MediaQueue.Play or something different, this fix will most likely allow you to fix the issue.

Several affected users have confirmed that they were able to prevent the apparition of new instances of the .NET Runtime Error 1026 error, by using the Programs and Features menu to essentially reinstall the entire Windows Media Player component.

If you haven’t tried doing this yet, follow the instructions below:

1. Press Windows key + R to open up a Run dialog box. Inside the text box, type ‘appwiz.cpl’ inside the text box and press Enter to open up the Programs and Features menu.
2. Once you’re inside the Programs and Features menu, click on Turn Windows features on or off. When you’re prompted by the UAC (User Account Control), click Yes to grant admin access.
3. Once you’re inside the Windows Features menu, scroll down through the list of features and expand the drop-down menu associated with Media Features. 
4. Next, uncheck the box associated with Windows Media Player and click Ok to effectively disable Windows Media Player. At the confirmation prompt, click on Yes to confirm the operation.
5. Wait until the operation is complete, then restart your computer in order to allow your computer to boot without the WMP components.
6. Follow steps 1 to 3 to return to the Windows Features screen, then check the box associated with Windows Media Player (under Media Features) to re-enable, then confirm the operation and wait for the process to complete.
7. Check Event Viewer and see if you can spot new instances of the .NET Runtime Error 1026.

If the issue is still not resolved, move down to the next potential fix below.

Method 5: Running SFC and DISM Scans

If none of the methods above have worked for you, it’s time to start troubleshooting for some kind of corruption affecting your system files that’s affecting the .NET framework. if the .NET Framework repair tool was not effective in your case, you should proceed by running a couple of built-in utilities that every recent Windows version has (SFC and DISM).

SFC (System File Checker) and DISM (Deployment Image Servicing and Management) are two tools capable of effectively identifying corrupted system files and replacing them with healthy equivalents.

Even though these 2 tools share some similarities, our recommendation is to run both in quick succession in order to improve your chances of fixing the corrupted system files.

Doing an SFC scan is an ideal place to start since it’s an entirely local tool that will not require you to have a reliable internet connection.

Note: After starting this procedure, it’s important to avoid closing the elevated CMD window even when the utility looks like it froze (this tends to happen with PC’s using traditional HDD). Wai patiently until the process is complete as interrupting the operation might cause logical errors on your HDD.

Once the SFC scan is complete, reboot your computer and deploy a DISM scan once the next startup is complete.

Note: This utility uses a sub-component of Windows Update to download healthy components to replace corrupted instances of system files. Because of this, you need to make sure that you have reliable Internet. 

Once the DISM scan has been completed successfully, restart your computer and check Event Viewers to see if you can spot new instances of the .NET Runtime Error 1026.

In case the same issue is still occurring, move down to the next potential fix below.

Method 6: Refresh every Windows Component

If none of the methods above have worked in your case, it’s very likely that you’re dealing with some kind of underlying system corruption issue that is affecting your .NET framework that no built-in utility is able to fix.

If this scenario is applicable, one of the last things you can do is to make sure that you are essentially refreshing every Windows component in order to eliminate any type of corruption that might be responsible for this issue.

When it comes to doing this, there are 2 procedures that you should consider using:

• Repair install (in-place repair) – This is the recommended procedure if you are not short of time and you want to go for a method that will allow you to preserve your personal files present on the OS drive. Doing a repair install procedure will require you to use compatible installation media. But the major advantage is that you get to keep your installed applications, games, personal media, and even some user preferences.
• Clean install – If you’re looking for a quick fix and you don’t have important data on your OS drive (or you have already backed it up), the procedure that makes the most sense is a clean install. This will not require you to use installation media (you can start it directly from the GUI menu of Windows).

Windows Server Identity Management Service (IdentitySvr) will not start. Event Viewer shows the following:

EventID.net saids the following:

«Since this is a problem with the application itself, unless you are the programmer, you cannot change it. So, what can be done is to try to install the latest version for that application or any hotfixes or contact the developer. In certain situations,
understanding the reason of the failure (the «exception») may help in identifying the nature of the problem and maybe determine ways to avoid it. For example, the System.Net.HttpListenerException, related to a problem with an HTTP request may be caused by
a network connection issue or maybe by the local TCP/IP configuration. Other exceptions may point to a permissions problem, lack of space, etc.»

Your help is appriciated.

Как исправить ошибку .NET Framework 1026

Определение «Net Error 1026»

Это наиболее распространенное условие «Net Error 1026», известное как ошибка времени выполнения (ошибка). Разработчики программного обеспечения, такие как Microsoft Corporation, обычно принимают .NET Framework через несколько уровней отладки, чтобы сорвать эти ошибки перед выпуском для общественности. К сожалению, некоторые критические проблемы, такие как ошибка 1026, часто могут быть упущены из виду.

Пользователи .NET Framework могут столкнуться с ошибкой 1026, вызванной нормальным использованием приложения, которое также может читать как «Net Error 1026». После возникновения ошибки 1026 пользователь программного обеспечения имеет возможность сообщить разработчику об этой проблеме. Microsoft Corporation вернется к коду и исправит его, а затем сделает обновление доступным для загрузки. Чтобы исправить любые документированные ошибки (например, ошибку 1026) в системе, разработчик может использовать комплект обновления .NET Framework.

Что генерирует ошибку времени выполнения 1026?

У вас будет сбой во время выполнения .NET Framework, если вы столкнетесь с «Net Error 1026» во время выполнения. Это три основных триггера для ошибок во время выполнения, таких как ошибка 1026:

Ошибка 1026 Crash — это распространенная ошибка 1026 во время выполнения ошибки, которая приводит к полному завершению работы программы. Эти ошибки обычно возникают, когда входы .NET Framework не могут быть правильно обработаны, или они смущены тем, что должно быть выведено.

Утечка памяти «Net Error 1026» — ошибка 1026 утечка памяти приводит к тому, что .NET Framework использует все больше памяти, что делает ваш компьютер запуск медленнее и замедляет вывод системы. Потенциальные триггеры могут быть бесконечным циклом, что приводит к тому, что работа программы запускается снова и снова.

Ошибка 1026 Logic Error — «логическая ошибка», как говорят, генерируется, когда программное обеспечение получает правильный ввод, но генерирует неверный вывод. Это видно, когда исходный код Microsoft Corporation содержит недостаток в обработке данных.

Большинство ошибок Net Error 1026 являются результатом отсутствия или повреждения версии файла, установленного .NET Framework. Как правило, любую проблему, связанную с файлом Microsoft Corporation, можно решить посредством замены файла на новую копию. В некоторых случаях реестр Windows пытается загрузить файл Net Error 1026, который больше не существует; в таких ситуациях рекомендуется запустить сканирование реестра, чтобы исправить любые недопустимые ссылки на пути к файлам.

Распространенные проблемы Net Error 1026

Net Error 1026 Проблемы, связанные с .NET Framework:

• «Ошибка в приложении: Net Error 1026»
• «Net Error 1026 не является приложением Win32.»

• «Файл Net Error 1026 не найден.»
• «Net Error 1026 не найден.»
• «Ошибка запуска в приложении: Net Error 1026. «
• «Net Error 1026 не выполняется. «
• «Отказ Net Error 1026.»
• «Неверный путь к программе: Net Error 1026. «

Ошибки Net Error 1026 EXE возникают во время установки .NET Framework, при запуске приложений, связанных с Net Error 1026 (.NET Framework), во время запуска или завершения работы или во время установки ОС Windows. Выделение при возникновении ошибок Net Error 1026 имеет первостепенное значение для поиска причины проблем .NET Framework и сообщения о них вMicrosoft Corporation за помощью.

Источник ошибок Net Error 1026

Проблемы Net Error 1026 могут быть отнесены к поврежденным или отсутствующим файлам, содержащим ошибки записям реестра, связанным с Net Error 1026, или к вирусам / вредоносному ПО.

В частности, проблемы с Net Error 1026, вызванные:

• Недопустимый Net Error 1026 или поврежденный раздел реестра.
• Вирус или вредоносное ПО, повреждающее Net Error 1026.

How to Fix .NET Runtime Error 1026

Several Windows users have opened up Event Viewer and discovered a lot of .NET Runtime Error 1026 errors that are happening in quick succession. Most affected users are reporting that whenever a new event of this kind is created, they also end up seeing an application error pop-up. This issue is confirmed to occur on Windows 7, Windows 8.1, and Windows 10.

NET Runtime Error 1026

After investigating this issue, it turns out that there are several different underlying causes that might be producing the .NET Runtime Error 1026. Here’s a list of potential culprits that might cause this error:

• 3rd party application conflict – As it turns out, you can see this particular issue occurring due to a conflict between two 3rd party processes or between a 3rd party service and a native Windows process. In most situations of this kind, you should be able to fix the issue by achieving a clean boot state and identifying the culprit via trial and error.
• Corrupted .NET Infrastructure files – If you’re constantly seeing new instances of this error inside Event Viewer, it’s possible that you’re dealing with some type of corruption that’s affecting the .NET Framework installation. In this case, the most efficient way of going about solving the issue is to run the .NET Repair Tool.
• Lauchpad.exe conflict with Windows Update – In the past, this issue started occurring as a result of a bad Windows Update that ended up breaking the existing functionality of Launchpad.exe. Affected users facing the same issue have confirmed that they managed to fix the issue by giving the admin account full control over the user’s folder and renaming the Launchpad.exe executable.
• Corrupted Windows Media Installation – Under certain circumstances, it’s possible;e to encounter this kind of issue due to a partially corrupted Windows Media Player dependency. If that’s the case, you should be able to fix the issue by using the Windows Features utility to reinstall the WMP package.
• System File corruption – Keep in mind that you can also experience this issue even if the corruption affecting your device is beyond the scope of the .NET Framework that you’re actively using. In this case, you should take the time to run DISM and SFC scans in an attempt to fix superficial cases of system file corruption. However, in most serious circumstances, you might need to go for a clean install or repair install procedure.

Now that you know every scenario that might be the underlying cause of this issue, here’s a list of methods that other affected users have successfully used to get to the bottom of this issue:

Method 1: Clean Boot Procedure

According to most documented cases, this issue can most likely occur due to some kind of conflict between two 3rd party programs or between a 3rd party program and a native Windows process. This is way more likely if you’re only noticing new instances of the .NET Runtime Error 1026 error popping up when you attempt to open a 3rd party application.

If this scenario is applicable, you can isolate and identify the culprit by starting your computer into clean boot mode and seeing if the issue still occurs.

This operation will ensure that your computer boots up in a mode that disallows the running of any 3rd party service, process, or startup item.

If you boot your computer into a Clean Boot state and you see that the issue stops occurring, you can go ahead and systematically re-enable every process and startup item and do regular restarts until you manage to pinpoint the culprit.

In case the same .NET Runtime Error 1026 error is still occurring even after you boot your PC into the clean boot, move down to the next potential fix below.

If a clean boot didn’t work for you, our recommendation is to proceed with a series of troubleshooting steps that will allow you to fix any underlying issues with the .NET redist packages that are currently installed on your computer.

Several affected users that were also struggling with this issue have reported that they finally managed to prevent new instances of the .NET Runtime Error 1026 error from occurring by running the .NET Framework Repair Tool – This tool will automatically scan your computer and fix any .NET dependencies that might be creating issues.

If you haven’t tried running the .NET Repair tool, follow the instructions below for step by step instructions on doing so:

1. Open your browser and access the Microsoft .NET Framework Repair tool download page. Once you’re inside the page, click on the Download button (under Microsoft .NET Framework Repair Tool). Downloading the NET Framework Repair tool
2. After you get to the next screen, start by checking the box associated with NetFxRepairTool.exe while unchecking everything else. Next, click on Next to advance to the next menu.
3. Once the download is complete, double-click on the installation executable that you’ve just downloaded, then click Yes when prompted at the UAC (User Account Control).
4. After you manage to open the Microsoft .NET Framework Repair Tool, follow the on-screen instructions and check the box associated with I have read and accepted the license terms when prompted by the ToS before clicking on Next to move forward. Initiating a repair using the .NET Repair tool
5. At this point, the utility should have already begun the scanning of the .NET dependencies installed on your computer. Wait patiently until the process is complete and avoid interrupting it to avoid additional issues.
6. Once the operation is finally complete, click on Next to automatically apply the repair strategy that the utility recommends. Applying the recommended fix for the .NET framework
7. Once the fix is successfully applied, click on Finish to complete the process. If you’re not prompted to restart automatically, do it yourself and see check Event Viewer once the nest startup is complete to see if the same kind of issue is still occurring.

If you already ran the .NET Framework Repair utility and you’re still seeing this kind of issue, move down to the next potential fix below.

Method 3: Renaming the Launchpad.exe (if applicable)

As it turns out, you can expect to see this error due to a new Windows Update that ended up breaking an existing Windows 10 functionality. Although the .NET Runtime Error 1026 error is not really indicative of this potential culprit, several affected users have confirmed that they were able to get Full Control permissions for the Users directory and renaming the Launchpad.exe to something different in order to prevent Windows from using it.

Note: If you have multiple users account on this computer, you need to do this for every user present inside the C:Users directory.

If you haven’t tried this method yet, follow the instructions below to obtain Full Control permissions in the Users directory and rename the main Launchpad executable:

Update: As far, this particular fix was only confirmed to work for Windows 10.

1. Start by ensuring that the user account you’re currently using is an administrator.
2. Next, navigate to the root directory of your OS drive (most likely C:/), right-click on the Users folder, and choose Properties from the context menu that just appeared. Accessing the Properties screen of Users
3. Once you’re inside the Properties screen, access the Security tab, select the Administrators group from the menu below, then click on Edit.Editing the permissions of the Administrators tab

Note: When prompted by the UAC (User Account Control Prompt), click Yes to grant administrative privileges.

Inside the Permissions for Users window, select the Administrators tab and ensure that the Allow box associated with Full control is checked. Modifying the permissions of Users

If you’re still spotting new instances of the .NET Runtime Error 1026, move down to the next potential fix below.

If you’re encountering this error while attempting to launch an application or game that needs to make use of a Windows Media Player dependency, you might be able to fix this issue by reinstalling the local installation of Windows Media Player.

Typically, you will be able to spot if this scenario is applicable by checking the Event ID log file. If it contains mentions of Microsoft.Xna.Framework.Media.MediaQueue.Play or something different, this fix will most likely allow you to fix the issue.

Several affected users have confirmed that they were able to prevent the apparition of new instances of the .NET Runtime Error 1026 error, by using the Programs and Features menu to essentially reinstall the entire Windows Media Player component.

If you haven’t tried doing this yet, follow the instructions below:

1. Press Windows key + R to open up a Run dialog box. Inside the text box, type ‘appwiz.cpl’ inside the text box and press Enter to open up the Programs and Features menu. Accessing the Programs and Features menu
2. Once you’re inside the Programs and Features menu, click on Turn Windows features on or off. When you’re prompted by the UAC (User Account Control), click Yes to grant admin access. Accessing the Windows Features menu
3. Once you’re inside the Windows Features menu, scroll down through the list of features and expand the drop-down menu associated with Media Features.
4. Next, uncheck the box associated with Windows Media Player and click Ok to effectively disable Windows Media Player. At the confirmation prompt, click on Yes to confirm the operation. Disabling the Windows Media Player component
5. Wait until the operation is complete, then restart your computer in order to allow your computer to boot without the WMP components.
6. Follow steps 1 to 3 to return to the Windows Features screen, then check the box associated with Windows Media Player (under Media Features) to re-enable, then confirm the operation and wait for the process to complete.
7. Check Event Viewer and see if you can spot new instances of the .NET Runtime Error 1026.

If the issue is still not resolved, move down to the next potential fix below.

Method 5: Running SFC and DISM Scans

If none of the methods above have worked for you, it’s time to start troubleshooting for some kind of corruption affecting your system files that’s affecting the .NET framework. if the .NET Framework repair tool was not effective in your case, you should proceed by running a couple of built-in utilities that every recent Windows version has (SFC and DISM).

SFC (System File Checker) and DISM (Deployment Image Servicing and Management) are two tools capable of effectively identifying corrupted system files and replacing them with healthy equivalents.

Even though these 2 tools share some similarities, our recommendation is to run both in quick succession in order to improve your chances of fixing the corrupted system files.

Doing an SFC scan is an ideal place to start since it’s an entirely local tool that will not require you to have a reliable internet connection.

Running an SFC scan

Note: After starting this procedure, it’s important to avoid closing the elevated CMD window even when the utility looks like it froze (this tends to happen with PC’s using traditional HDD). Wai patiently until the process is complete as interrupting the operation might cause logical errors on your HDD.

Once the SFC scan is complete, reboot your computer and deploy a DISM scan once the next startup is complete.

Running a DISM scan

Note: This utility uses a sub-component of Windows Update to download healthy components to replace corrupted instances of system files. Because of this, you need to make sure that you have reliable Internet.

Once the DISM scan has been completed successfully, restart your computer and check Event Viewers to see if you can spot new instances of the .NET Runtime Error 1026.

In case the same issue is still occurring, move down to the next potential fix below.

Method 6: Refresh every Windows Component

If none of the methods above have worked in your case, it’s very likely that you’re dealing with some kind of underlying system corruption issue that is affecting your .NET framework that no built-in utility is able to fix.

If this scenario is applicable, one of the last things you can do is to make sure that you are essentially refreshing every Windows component in order to eliminate any type of corruption that might be responsible for this issue.

When it comes to doing this, there are 2 procedures that you should consider using:

• Repair install (in-place repair) – This is the recommended procedure if you are not short of time and you want to go for a method that will allow you to preserve your personal files present on the OS drive. Doing a repair install procedure will require you to use compatible installation media. But the major advantage is that you get to keep your installed applications, games, personal media, and even some user preferences.
• Clean install – If you’re looking for a quick fix and you don’t have important data on your OS drive (or you have already backed it up), the procedure that makes the most sense is a clean install. This will not require you to use installation media (you can start it directly from the GUI menu of Windows).
