UPEK Fingerprint reader on Windows Vista Ultimate 64-bit editionq

Hey guys,

 

I just bought a new Dell Latitude D630 with a fingerprint reader. I believe I have  UPEK fingerprint reader on my system. Since I did not have any OS pre-installed, I did not have all the drivers preinstalled on my laptop. I installed Windows Vista Ultimate 64-bit OS later on. Now, when I go to my Device Manager, I see something as "Biometric Coprocessor" with a Yellow exclamation mark. It seems I don't have drivers installed for my fingerprint reader. I tried to install the Windows Vista 32-bit drivers, but got an error that my OS does not support it. Does any one know if Windows Vista Ultimate 64-bit OS does not support fingerprint authentication? If anyone's used it, can anyone please direct me to a place where I can download the drivers from? Thanks.
