You can go directly to the creative site and grab drivers
for your card specifically and they will work just fine. The manufacturer drivers usually work the best if you can use them but creative has drivers that will work just fine on their page.
I actually had to get the drivers from the creative site when I installed 7100 32bit because my discs were just to old. If i install from the discs I have issues until I update to the latest drivers. So now I have made a habit of just grabbing the latest drivers right from creative and so far it works every time.
I am using the X-Fi Fatal1ty card in this machine and an X-Fi Platinum in the second machine.
