Is that path in the 64-bit portion of the Registry? If so, Visual Patch may not be able to access it directly because it is running as a 32-bit process, without turning the Registry redirection off.
There is an API call that can be used to turn Registry redirection off, but it isn't available in Visual Patch 2.0.
You should be able use a DLL to do that, though. In fact I think someone on these forums (Eagle?) already made such a DLL, so you might be able to find a solution with a forum-wide search.
