Have you tried Tools / Options / Debugging / JIT and disabling VS as the JIT debugger? That way the system should fall back to the default JIT debugger.

Thanks for your answer, but I have tried and it does not solve the problem.
When I disable JIT debugging in the options, I receive the message "JIT
Debugging is disabled. To enable JIT Debugging, from Visual Studio .NET go
to Tools/Options/Debugging/JIT Sesstings". When I re-enable JIT debugging in
the options, I receive the "JIT debugging failed with the following error:
0x800405a6" message again.
Seems to me that maybe some registry/config settings are not reset when you
desinstall VS.NET ?
Any other idea ?

You could try vs7jit.exe /regserver to re-register the key component.
Which JIT are you trying to enable (native/clr/script)?
Do you get the error when enabling the other JIT options?

Hi Andy,
I tried vs7jit.exe /regserver, but without success.
Here is the problem. I am working with a console application. On my PC, when
there is an exception, I receive a dialog box showing an error (JIT
debugging failed with the following error: 0x800405a6). On another PC, I
receive the correct dialog box asking me which debugger I want to use (An
exception 'System.Exception' has occurred in ConsoleApp.exe. Possible
Debuggers:... Do you want to debug using the selected debugger ?).
What do I have to do to correct the configuration of my PC, knowing that
desinstall/reinstall of VS.NET and the .NET Framework doesn't work ?
Thanks,
Benoit
