Thanks for getting back. From many years ago: I had massive problems installing a program in windows NT, the program kept failing on file copy. But, to keep a long story short, I called tech support. Told them my problem, which generated a loooong pause finally the response was Did you disable your anti virus? My answer: NO. his reply Well, it says to in the setup instructions. ( Boy, did I feel like a fool).
So now my advice is to disable the antivirus when installing programs or drivers.
