Loverboy1,
Here is the correct installation procedure:
The batch files won't copy to any location other than default CFS3 location (C\Program Files\Microsoft Games.
Simply copy your vanilla install to the default location, C:\Program Files\Microsoft Games, and then install CFS3 PTO Rising Sun.
BEFORE YOU RUN RS EVEN ONCE, just move it to your desired location.
Everything should be OK after that.
Then remove the vanilla from the default location.
Again, I can't stress enough to follow all install instructions EXACTLY.
