Just in time debugger error

Problem

User performs an action in Controller. User receives an error message.

Symptom

Depending on what you are doing, you will receive a different error message. Below is one example of a screen error:

Visual Studio Just-In-Time Debugger
An unhandled win32 exception occurred in EXCEL.EXE [6920]. Just-In-Time debugging this exception failed with the following error: No installed debugger has Just-In-Time debugging enabled from Tools/Options/Debugging/Just-In-Time.
Check the documentation index for ‘Just-in-time debugging, errors’ for more information.
[OK]

Cause

The client PC has been configured to use the Visual Studio Just-In-Time Debugger. This can potentially mask (hide) the ‘true’ problem, because (without the Just In Time debugger) there would probably be a more sensible/intuitive/well-known error message to appear.

Resolving The Problem

Reconfigure Internet Explorer so it does not use the Visual Studio Just-In-Time Debugger. After this is done, error messages should be more informative.

Steps:

1. Launch Internet Explorer
2. Click ‘Tools — Internet Options’
3. Click the ‘Advanced’ tab
4. Look down until you find the ‘Browsing’ section
5. Tick the box ‘Disable script debugging (Internet Explorer)’
6. Tick the box ‘Disable script debugging (Other)’
7. Click OK
8. Close Internet Explorer
9. Test

If Controller crashes from now on, you should find a more helpful error message appearing.

Issue:

When launching an AutoCAD product, it freezes and generates the error:  

Application does not support just-in-time (JIT) debugging. Contact the application author for more information.

Causes:

Just-In-Time debugging is a feature that launches the Visual Studio debugger automatically when a program, running outside Visual Studio, encounters a fatal error. Just-In-Time debugging allows you to examine the error before the application is terminated by the operating system. The Visual Studio debugger does not need to be running when the error occurs.
 

Solution:

Microsoft offers a solution to resolve this issue on Microsoft Community

• Enable/disable Just-In-Time debugging in Microsoft Visual Studio:

1. Go to ‘Tools’ then ‘Options’.
2. In the ‘Options’ dialog box, select the ‘Debugging’ folder.
3. In the ‘Debugging’ folder, select the «Just-In-Time» page.
4. In the ‘Enable Just-In-Time’ debugging of these types of code box, select or clear the relevant program types: ‘Managed’, ‘Native’, or ‘Script’.

Note:  To enable or disable Just-In-Time debugging, you must be running running Administrator privileges.  Enabling or disabling Just-In-Time debugging utilizes the registry key, and Administrator privileges are required to change that key.

1. Click ‘OK’.  

• In the event Visual Studio is not installed, disable script debugging in Microsoft Internet Explorer then check if the pop-up is eliminated:

1. Open ‘Internet Explorer’. 
2. Click on ‘Tools’ then ‘Internet Options’ then the ‘Advanced’ tab. 
3. Under the ‘Browsing’ section, uncheck the following:
   • Disable script debugging (Internet Explorer).
   • Disable script debugging (Other).
   • Display a notification about every script error.

If disabling Just-In-Time Debugging does not resolve the issue:

• Examine the exception error more closely to discover which application the exception is being thrown and the troubleshooting directions the error gives.
• If an error of «Fatal Error: Unhandled e0434352h Exception at… » occurs with the JIT error, do the following troubleshooting steps (see:  «FATAL ERROR: Unhandled e0434352h Exception at…» when starting AutoCAD products).
• Uninstall then reinstall the application (for AutoCAD products, (see Recommended uninstall and reinstall procedures for AutoCAD).
• For non-Autodesk (third party) components or add-ons, contact the author of that application for further assistance. For example, the exception may be seen with Microsoft .NET or third party add-ins installed in the AutoCAD product.
