How do I enable “JIT Debugging” for Microsoft .NET Framework In Windows 7?

Question

How do I enable “JIT Debugging” for Microsoft .NET Framework in Windows 7? A “dialog box” warning window with the red X icon pops up repeatedly/seemingly randomly , lists a long series of what looks to me like command line or etc programming, or events,  (I’m not a programmer, obviously), and then says:

Quote:

"Unhandled exception has occurred in your application.....The system cannot find the file specified...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."

End quote

As mentioned, I don't have programming skills/language, but I've been successful in past following a tech's exact and detailed directions, going into registry (or whatever/wherever in the bowels of the OS), finding a specified destination, modifying/retyping a specific file/command/etc, and managing to fix the problem without my computer melting.

Anyone?  With skillz?  Help, please?

See the end of this message for details on invoking 

just-in-time (JIT) debugging instead of this dialog box.

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