What is a runtime environment?

Runtime basically means everything you require to run a program. Which includes environment variables, directory structure, common libraries etc. This can also be a virtual machine like

  • JRE (Java Runtime Environment)
  • CLR (Common Language Runtime) for .net framework

The target would be JRE or CLR for your program, need to decide by you. As soon as you execute any program, it’s in run time.

JRE vs JDK

JRE JDK
Stands for Java Runtime Environment Stands for Java development kit
To run Java programs, you need JRE Helps to build Java programs and applets
Platform dependent contains libraries and supporting tool Platform dependent contains tools development and debugging
JRE does not contain a development kit. JDK includes JRE also to execute the program
Simple JRE VS JDK

What are the causes of the «Java Runtime environment not found» error

  1. Java is not installed in your system
  2. Java installation not completed (due to errors)
  3. Environment variables of Java are not set
  4. Java conflict due to more than one Java Runtime installation

Because JRE is platform-dependent, I have covered java installation, variable setup and un-installation for Windows and Ubuntu both.

The Java Development Kit (JDK), the Java Virtual Machine (JVM), and the Java Runtime Environment (JRE) form a trio of Java platform components for developing and running Java apps.

A runtime environment is a piece of software designed to run other software. For example, as the runtime environment for Java, the JRE contains the Java class libraries, the Java class loader, and the JVM.

So if you don’t have JRE installed or you have an older version of the software, you might encounter one of the following messages:

  • Error: Could not find Java SE Runtime Environment – you don’t have the Java SE version installed on your system
  • This application needs version 1.x or higher of the Java Runtime Environment – you should update your Java version to the latest you can find on the official website
  • A Java Runtime Environment(JRE) or Java Development Kit (JDK) must be available to run this app – like the first error, check if you have installed JRE or JDK and if not, install them

Today’s guide will explore the most efficient and easy methods to resolve the Java Runtime Environment not found and the other similar errors with Java. Read on for more details.

Why is JRE not installed?

In Windows and macOS, installing the Java Developmental Kit (JDK) in previous releases optionally installed a Java Runtime Environment (JRE).

However, with JDK 11, Oracle removed JRE to be installed optionally. Therefore, with JDK 11 release, the JRE or Server JRE is no longer offered, and only the JDK is provided.

Also, the Java Runtime Environment not found it could be caused by several other reasons, which we have listed below.

  • Java is not installed on your PC.
  • Java installation was not completed due to some errors.
  • The environment variables of Java are not set.
  • You might have more than one Java Runtime installation.
  • A Windows misconfiguration can also trigger this problem.

Не устанавливается Java на Windows 7, 8 или 10 — произошла ошибка. Решение.

Программное обеспечение Java используется как платформа для очень многих программ под Windows и являет признанным стандартом для разработки различных приложений и игр. Оно предоставляет уйму возможностей для программиста, а расплачиваться за это приходится пользователям в виде необходимости обязательной установки библиотек Джава или даже Java Virtual Machine на компьютер или ноутбук. И ладно бы всё проходило «без сучка и задоринки», но очень часто ПО JAVA не устанавливается и выдаётся ошибка установки. Что делать и как его всё-таки успешно инсталлировать в систему Windows? Вот несколько советов.

1. Обычно, при загрузке программного обеспечения с официального сайта, Вы скачиваете специальный веб-установщик, который будет затем сам тянуть нужные библиотеки через подключение к Интернет. Но тут может включить в игру антивирус или фаервол, который может расценить это как вирусную активность и заблокировать доступ в интернет установочному приложению. Поэтому попробуйте скачать полноценный офлайн-установщик отсюда — ссылка, а затем попробовать установить Джава через него. Не удивляйтесь, что он весит около 50 Мегабайт, в то время, как веб-установщик почти в 50 раз меньше. Это нормально.

2. Если у Вас до этого уже стояла более старая версия Java — попробуйте его удалить и поставить заново через Панель управления Windows.

3. Проверьте свою операционную систему Windows 7, 8 или 10 с помощью хорошей антивирусной программы. Например, DrWeb CureIt или Kaspersky Antivirus. Очень часто вредоносные программы маскируются под системные библиотеки и затем не дают их обновлять.

4. Почистите реестр Виндовс с помощью специальной утилиты. Например, CCleaner.

Именно ошибки в реестре часто являются причиной того, что ПО Java не устанавливается на компьютер.

5. Попробуйте почистить системные папки:
C:ProgramFilesJava
и
C:ProgramFilesCommon FilesJava
Иногда файлы, оставшиеся от старых версий приводят к ошибке установки Джава.

6. Попробуйте обновить компоненты Windows с помощью Центра обновлений. Может случится такое, что ошибка установки Java Runtime Environment возникает даже из-за устаревшей версии Internet Explorer.

7. Скачайте фикс-файл с исправлениями здесь и примените изменения в реестре.

Не устанавливается Java на Windows

Работа некоторого программного обеспечения зависит от вспомогательных утилит и приложений. Поэтому пользователи желают быстрее решить проблему, когда не работает уже установленная Java. Ошибки могут возникнуть и раньше, когда не устанавливается приложение Java на компьютер с ОС Windows. Разберемся в каждой проблеме и узнаем, что делать.

Почему Java не скачивается

Чтобы ответить на вопрос, что делать, если модуль Джава не скачивается на компьютер, важно понять, почему установщик не выполняет функций по загрузке библиотек.

Загружаемый на компьютер файл не содержит требующихся компонентов, а просто скачивает необходимые файлы из виртуальных библиотек через интернет. Важно проверить работу файрволов, антивирусов и браузеров. Такое ПО блокирует фоновую загрузку Java.

Решение проблемы достигается двумя вариантами: настройка приложений или скачивание полноценного установщика с нашего и официального сайта Джава. Обновите антивирус, просмотрите параметры блокировок.

Ошибки при установке

Если файл скачался, а Java не устанавливается на Windows 7, 8, 10 или XP, то проблема глубже.

Способы решения проблемы:

  1. Очистить компьютер от мусора, освободив при этом реестр. Удобнее провести процедуру через CCleaner.
  2. Полностью очистить папки по следующим адресам: «C:ProgramFilesJava» и «C:ProgramFilesCommon FilesJava». Какой-то из файлов мог быть запущен, поэтому не удалился на предыдущем этапе.
  3. Ошибка установки, возникающая после очистки реестра, говорит о том, что на Windows не обновлены компоненты ОС. Даже устаревший браузер от Microsoft может доставлять массу неприятностей при установке других программ.

С остальными ошибками Джава на Виндовс стоит познакомиться поближе.

Error Java Installer

Если не запускается установщик программы Java, обратите внимание на подключение к интернету. Лучше продолжить процесс в автономном режиме, скачав исполняемый файл с соответствующей пометкой.

Когда установленная Джава не открывается, то используется программа Windowsfix. ПО помогает в устранении сотен ошибок, включая те, что встречаются на Java.

Ошибка 1603

Ошибка Java с пометкой Error Code: 1603 появляется в процессе установки обновления. Причина до сих пор не выявлена разработчиками.

Предлагаются следующие способы решения:

  • Переустановка приложения с удалением. Предполагается, что сбой и ошибка 1603 возникают из-за некорректной загрузки ПО на компьютер. Поэтому сотрите информацию об утилите, очистите операционную систему от следов Джавы и скачайте файл для автономной установки программы.
  • Отключение отображения контента Джава. Проблема исправления ошибки с кодом 1603 может крыться в использовании утилиты при работе с браузерами. Перед установкой снимите флажок в панели управления приложения на вкладке «Безопасность».

После переустановки приложения верните флажок на место.

Ошибка 1618

Чтобы исправить ошибку Java 1618, воспользуйтесь следующей инструкцией:

  1. На системном диске должно быть достаточно места, чтобы исполняемый файл без труда устанавливал программу. Вес Джавы – 158 Мб.
  2. Скачайте пакет для автономной установки ПО.
  3. Папку, где до этого хранилась Джава, нужно очистить вручную.
  4. Удалите ненужные файлы в реестре, используя CCleaner.
  5. Отключите антивирусы.
  6. Установка программы начинается заново.

Причина ошибки 1618 при установке Java на компьютер разработчиками не выяснена.

Unable to install Java

Разработчики программ из Microsoft знают, что делать с ошибкой Unable to install Java. Они рекомендуют: «Компоненты файлов с расширением .jar блокируются системой или антивирусом. Для решения проблемы установка проводится в безопасном режиме».

Java Destination Folder

Ошибка папки назначения Destination Folder возникает на 32-разрядных версиях ОС Windows. Для решения проблемы создается новая папка в следующей директории: «C:Program Files (x86)». Если есть какое-то содержание, то его нужно удалить.

При установке программы путь указывается в новую папку.

Не запускается Java

Для начала убедитесь, что при установке не возникало неполадок и системных сообщений.

Как запустить программу Java, если возникают ошибки:

  1. Перезапустите браузер для активации новой версии программы. Иногда после обновления приложение Джава запускается только после перезагрузки ПК.
  2. Разрешите выполнять функции среды Java в используемом браузере. Работа с указанными программами может быть выключена и на панели управления приложением.
  3. Подключаемый модуль Джава должен быть активирован на запускаемом браузере. Если программа не открывает видео или игры, проверьте не только ее настройки, но и, например, Оперы или Chrome.

Приложение работает постоянно, но в фоновом режиме. Иными словами, вопрос, как открыть программу Java на компьютере, не имеет ответа. Главное – настроить взаимодействие с браузерами.

Let’s understand some basic concepts of Java runtime first. Check out this post, if you are getting a java command not found error.

What is a runtime environment?

Runtime basically means everything you require to run a program. Which includes environment variables, directory structure, common libraries etc. This can also be a virtual machine like

  • JRE (Java Runtime Environment)
  • CLR (Common Language Runtime) for .net framework

The target would be JRE or CLR for your program, need to decide by you. As soon as you execute any program, it’s in run time.

JRE vs JDK

JRE JDK
Stands for Java Runtime Environment Stands for Java development kit
To run Java programs, you need JRE Helps to build Java programs and applets
Platform dependent contains libraries and supporting tool Platform dependent contains tools development and debugging
JRE does not contain a development kit. JDK includes JRE also to execute the program

Simple JRE VS JDK

What are the causes of the «Java Runtime environment not found» error

  1. Java is not installed in your system
  2. Java installation not completed (due to errors)
  3. Environment variables of Java are not set

When trying to open a Java .jar file through the command prompt, such as using the command “Java -Jar xxxx.jar”, you might encounter the following error message:

Error: opening registry key ‘SoftwareJavaSoftJRE’

Error: could not find java.dll

Error: Could not find Java SE Runtime Environment.

This could be due to several factors, including but not limited to:

  • Corrupted registry
  • Missing Java path in your Environment Variables
  • Java installation folder being moved

For example, we encountered this issue when updating Java SE to the latest version – we likely previously had a 32-bit Java installation, and when running the 64-bit Java installer, our Java path changed.

The Java Development Kit (JDK), the Java Virtual Machine (JVM), and the Java Runtime Environment (JRE) form a trio of Java platform components for developing and running Java apps.

A runtime environment is a piece of software designed to run other software. For example, as the runtime environment for Java, the JRE contains the Java class libraries, the Java class loader, and the JVM.

So if you don’t have JRE installed or you have an older version of the software, you might encounter one of the following messages:

  • Error: Could not find Java SE Runtime Environment – you don’t have the Java SE version installed on your system
  • This application needs version 1.x or higher of the Java Runtime Environment – you should update your Java version to the latest you can find on the official website
  • A Java Runtime Environment(JRE) or Java Development Kit (JDK) must be available to run this app – like the first error, check if you have installed JRE or JDK and if not, install them

Today’s guide will explore the most efficient and easy methods to resolve the Java Runtime Environment not found and the other similar errors with Java. Read on for more details.

Why is JRE not installed?

In Windows and macOS, installing the Java Developmental Kit (JDK) in previous releases optionally installed a Java Runtime Environment (JRE).

However, with JDK 11, Oracle removed JRE to be installed optionally. Therefore, with JDK 11 release, the JRE or Server JRE is no longer offered, and only the JDK is provided.

Also, the Java Runtime Environment not found it could be caused by several other reasons, which we have listed below.

  • Java is not installed on your PC.
  • Java installation was not completed due to some errors.
  • The environment variables of Java are not set.
  • You might have more than one Java Runtime installation.
  • A Windows misconfiguration can also trigger this problem.

How do I fix the Java runtime environment not found?

1. Run Windows troubleshooter

  1. Select Start, and click on Settings.
  2. Choose Update & Security, and then click Troubleshoot.
  3. Select the type of troubleshooting you want to run, then select Run the troubleshooter.
  4. Allow the troubleshooter to run and then answer any questions on the screen. 

Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.
We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.
Click here to download and start repairing.

You can try the recovery options if you see a message that no changes or updates are necessary. This is a built-in troubleshooter tool from Windows 10.

2. Download Java Runtime Environment (JRE)

  1. Download JRE from the official website.
  2. Choose if you need a 32bit or a 64bit architecture of JRE based on your PC specifications.
  3. Click on the Agree and download button to start the actual download.
    download JRE

If you don’t know which version of Java is the correct version for your system, you can find out by searching in the Start menu the term System Information.

It would be best if you opened the first option that appears after the search and then checked the value under System Type (32-bit or 64-bit).

These are the errors I get when I try to run a simple java version in the command window.enter image description here

I followed the advice on Error: Registry key ‘SoftwareJavaSoftJava Runtime Environment’CurrentVersion’?.
When I went on regedit, here’s what I saw

Which meant that there was nothing to change — right runtime version. I then did the next step which was to «delete all previous versions of Java (using «Programs and Features» uninstall process) and then re-install just the version you want to work with»
However, that didn’t work either……
Here is my current java directory(see that i have everything installed)
enter image description here

And my current environmental variables are

JAVA_HOME - C:Program FilesJavajdk1.7.0_71

Path - C:Program FilesJavajdk1.7.0_71bin

which i believe are correct as well from http://www.oracle.com/technetwork/java/javase/install-windows-189425.html

Does anyone know how i can get rid of this issue? I could do one more uninstall/install but I think that be a waste of time and won’t make a difference.

I want to thank @almas-shaikh for this answer. His comment made me check over C:Program FilesJavajdk1.7.0_71jrebin and see that there was no java.dll library file inside that directory. What I did next was just deleting the jdk and reinstalling it via jdk-7u71-windows-x64.exe executable.
Now when I execute java -home, I get enter image description here

Now the part I don’t get is how the java.dll library file was deleted in the first place……

I had similar problem. Turns out, even when you have 64-bit OS, your browser is most likely 32-bit and therefore your JAVA too. You need to manually install 64-bit JAVA.

I hope that will help.

try adding «%JAVA_HOME%bin;» in the Path section instead of this «C:Program FilesJavajdk1.7.0_71bin», should make no difference but just try it like this.

I haven’t seen this answer, but this is how I ran into the problem and then solved it.

I had Java 14.0.2 installed and I needed IntelliJ and Maven installed. This computer is an enterprise computer so I didn’t have much saying on the installation process. I suppose IntelliJ came with Java 10.0.1 or that IT installed it as part of their process and it of course threw all my system out of the window.

So to fix this, I had to get someone from IT to unlock the admin things for me, and then:

  • I deleted the JRE paths with 10.0.1
  • Under the Windows tool to uninstall software, I deleted Java 10.0.1 JRE and JDK.
  • Under the Java directory, also moved or deleted those folders
  • And then I tested IntelliJ and the Terminal with java -version and javac -version to check if I was getting the same results (got 14.0.2, nice, that is what I was expecting)
  • And then checked Maven with mvn -version for the apache feedback as well, which will also return which JDK it’s running.

No need to fiddle with registry, or even restart the computer (just to restart the Terminal after Path changes).

When trying to open a Java .jar file through the command prompt, such as using the command “Java -Jar xxxx.jar”, you might encounter the following error message:

Error: opening registry key ‘SoftwareJavaSoftJRE’

Error: could not find java.dll

Error: Could not find Java SE Runtime Environment.

This could be due to several factors, including but not limited to:

  • Corrupted registry
  • Missing Java path in your Environment Variables
  • Java installation folder being moved

For example, we encountered this issue when updating Java SE to the latest version – we likely previously had a 32-bit Java installation, and when running the 64-bit Java installer, our Java path changed.

Error output when trying to run Java commands in Command Prompt.

Luckily, this is fairly easy to fix, as it just requires addressing one of the above problems with the appropriate solution. Follow our steps below to get your Java commands via command prompt working again, and leave a comment in the comments section if you encounter any further issues (or know of a better solution).

  1. Delete all previous versions of Java (using “Programs and Features” uninstall process). If java folder is remains in “C:/Program Files/…”, please delete it.
  2. Clean up your registry (delete your java key):
  3. Go to Start and then Run
  4. Type in ‘regedit’ in the edit field
  5. Go to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Uninstall
  6. Under this Uninstall folder you will find many registry entries within curly brackets.
    Regedit uninstall pathway.
  7. Click on Edit tab and then Find
  8. Note: Highlight Uninstall folder before performing search for particular registry.
  9. Enter version string as value to find corresponding registry entry to be deleted.
  10. Once you find registry key, highlight that key and then Right click on it and choose Delete
  11. Confirm the delete and click Yes

Steps for finding registry keys for any version of Java 7

  • Type 1.4.2_18 in search field, finds registry key for jre1.4.0_18

Reinstall Java and set system variable JAVA_HOME to your JRE (or JDK) path.

Eg:

JAVA_HOME - C:Program FilesJavajdk1.7.0_71

Path - C:Program FilesJavajdk1.7.0_71bin

You can check if this was a successful solution with the following commands

echo %JAVA_HOME%

java -version

Manually open command window to Java pathway.As a side note, you can also launch a command prompt directly from within the Java folder – navigate to your C:Program FilesJavabin folder (or wherever your Java is installed), hold Shift + Right click inside the window, and click “Open a command window here”.

I’ve been working on Aptana Studio and some JRE required software for a bit of time now , but since yesterday something quite odd happened, as suddenly the software that requires it threw me an error No Java virtual machine was found . Last thing I did before that was restoring my system files permissions thought safe mode as I had some trouble with that , could this have anything to do with it ?

I’ve tried installing JRE once again , no results. However when I run

/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version

I do get the following

java version "1.7.0_55"
Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)

Aptana gives me the following error

No Java virtual machine
was found after searching the following locations:
/Applications/Aptana Studio 3/AptanaStudio3.app/Contents/MacOS/jre/bin/java
java in your current PATH

And other software such as Spine won’t simply start.

My .bash_profile is the following :

PATH="/Library/Frameworks/Python.framework/Versions/3.4/bin:${PATH}"
PATH="/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home/bin:${PAT$
export PATH
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home

The output of echo $PATHis the following

The output of echo $JAVA_HOME is the following

/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home

And Java invocations on the terminal work.

Guidance will be highly appreciated.
