The CDC82860-468D-4D4E-B7E7-C298FF23AB2C ID in the registry is found to be InProcServer32

The error appears to occur at login.

The user has a group policy enforced roaming profile and is an admin for this server.

Presumably it is a 32 bit COM app that is causing this, but how do I find out which one?
