just in time debugger error

I using an windows XP since almost 7 years, never reinstalled.
Everything was fine… OK, maybe it is too slow for now days, but it is runing on a Pentium4 (max speed 3.4 GHz).
So, everything was fine until today, after uninstalling some unused software applications after the reboot I got tens of times messages like

An unhandled win32 exception occurred in mscorsvw.exe [NNNN].
Just-In-Time debugging this exception failed with the following error: No installed debugger has Just-In-Time debugging enabled.
In Visual Studio, Just-In-Time debugging can be enabled from Tools/Options/Debugging/Just-In-Time.

Check the documentation index for 'Just-in-time debugging, error' for more information.

Where NNNN is some random(?!) number.

just in time debugger error

After few restarts and googling the only working solution was to delete next two keys from the registry and restart.

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\DbgManagedDebugger
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug\Debugger

To modify the windows xp registry start a prompt command window (cmd) and type regedit or regedit.exe

Hope that this will help other people.
