Just-In-Time Debugger : disable pop-up window and still be able to debug

Fri, 01 Nov 2019 13:55:00 +0000

Hello,

Here is my goal :

I don't want to see the JIT (Just-In-Time) pop-up window asking to select a debugger.
But I still want to debug some scripts when I manually attach the process "w3wp.exe" in Visual Studio.

It's interesting if :
1. You're working in a test environment and your script doesn't give the same result as the one in your local machine.
2. You're not the only developer to work in a development environment.

In overflow, the solution about disabling JIT pop-up window corresponds to fully disable JIT.

So, if you rename the following folders, it's like having disabled JIT on your machine or server :
1. C:\Program Files\Common Files\Microsoft Shared\VS7Debug
2. C:\Program Files (x86)\Common Files\Microsoft Shared\VS7Debug

In most of the cases, it's the solution you're looking for !

To reach my goals, I first checked if the following folders are correctly named :
1. C:\Program Files\Common Files\Microsoft Shared\VS7Debug
2. C:\Program Files (x86)\Common Files\Microsoft Shared\VS7Debug

And finally, I renamed the .exe file "C:\Windows\System32\vsjitdebugger.exe", responsible for the pop-up window asking to select a debugger.

If you want to cancel this behavior, you have to rename the file correctly and restart the machine or server.

Kind regards,

Eric
