Trying to run the Conflict Detector. It stops with a problem and says that there is no JIT debugger available.

I have .NET installed.

What, in this context, is this JIT debugger and how do I find it?

The JIT debugger is used to debug any runtime exceptions that might occur during the course of the application's use. It wouldn't be of much use to the end user, unless he/she intends to much around in app.'s crash dump. You'll need M$ Visual Studio to use the feature.
