Hmmm... interesting that it would be looking for a file in XP thats not found in Vista...
Unfortunately, there's not much that can be done. Messing about in the system files is a sure way to crash your computer. Vista isn't known for it's friendliness to older programmes, is there any chance you can load it up on an XP machine?
Also, a search of my machine didn't turn up anything, but it may just be confused because windows isn't C, it's D. Seems to mess with it's head.
