Windows 10: JIT Debugging pop up error program worked before must have been an update that loused it up

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

I am using a Chinese Laser Engraver. I had difficulties installing the firmware originally due to this same pop up, I am currently getting. Support from the manufacturer is impossible (language barrier). I somehow corrected the error and the software worked for a month until today. I looked at my previous settings "Advanced Internet Settings" I disabled both script Debugging. I didn't have "Visual Studio" software installed so I wasn't able to follow any other solutions in the community. I did install Visual Studio, but couldn't figure out what I needed to do.

WHY DOES THIS HAPPEN EVEY TIME.

I have another Engraver where every time MS has an update I have to reinstall drivers firmware etc. JEEZ!

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Hi Alex,



Thank you for posting your query in Microsoft Community. Let me help you.



I suggest you to follow the below procedure and check if it helps.

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.



To enable/disable Just-In-Time debugging

In Visual Studio,

• 
  On the Tools menu, click Options.
  
• 
  In the Options dialog box, select the Debugging folder.
  
• 
  In the Debugging folder, select the Just-In-Time page.
  
• 
  In the Enable Just-In-Time debugging of these types of code box, select or clear the relevant program types: Managed, Native, or Script.
  

To disable Just-In-Time debugging, once it has been enabled, you must be running with Administrator privileges. Enabling Just-In-Time debugging sets a registry key, and Administrator privileges are
required to change that key.

• 
  Click OK.

Hi MaryMcKayZO

Rest assured, enabling JIT (Just in Time) Debugging on your PC will cause no side effects, it is totally safe to enable that on your PC . . .
