Help! Just-In-Time Debugging (JIT)

Hello everyone,
I recently downloaded a game on the Steam platform, and once installed, when I try to launch it, an error message appears, and I don't understand anything! Yet I have the latest version of Net Frameworks, and when I run "dxdiag," DirectX doesn't report any errors... What should I do please??? I've been searching for an answer on the internet for 2 days, but I can't find any... Please help me...

Here is the error message that appears in a new window:

Please refer to the end of this message for more details on the just-in-time (JIT) debugging call instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the configuration file for this application or machine (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 just-in-time debugging is enabled, unhandled exceptions will be sent to the JIT debugger registered on the machine instead of being handled by this dialog box.
Configuration: Windows Vista Firefox 3.0.6

  1. Hello,

    I also had a similar problem to yours, I received good advice so try this:

    When your error message appears, do not close the window, press Ctrl - Alt - Delete and open the task manager, check the APPLICATION tab for the offending program, then right-click and select GO TO PROCESS and see where the problem comes from.

    Hoping to have helped you.

    Best regards.
    1. Thank you very much, that works for me.
    2. uh, how do you see the problem?

    4. I have this problem too, but on top of that my task manager is blocked!
      What should I do?
    5. Hello,
      I do everything you tell me, but once in "go to the process," I don't know what the problem is.
