************** 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.

What program are you trying to execute?

What XP Service Pack are you on, 2 or 3?

Do you have .NET version 3.5 or 4 installed, or just 2.0? That error appears to be a v2.0 error. Depending on the program that's causing this, it may be advantageous to update your .NET to a current version if that's needed.

Just another stupid saying...

Actually the .NET 4.0 looks like it only supports XP SP3, and support from MS with XP SP2 ends this month (7-13-10).

You could also try this .NET verifier tool to make sure all your components are installed properly:

Other than installing service Pack 3 on your XP system, I'm not sure, and am no .NET expert, but I have dealt with it in that all the necessary components, prerequisites and requirements need to be met in order for it all to work properly.
