ViDock + nvidia quadro nvs 450 = can't install. HELP!

[AMATX]

Hi all - just got in an nvidia quadro nvs 450 card and am trying to install drivers for it to run in a ViDock/ExpressCard box. Downloaded the drivers, but when I run the utility, I get the following error message:

This graphics driver could not find compatible graphics hardware.

Installation won't let me continue.

I tried booting up the box w/ViDock attached, using my current drivers and Windows doesn't see the card, even though the ViDock box appears to be working correctly(it worked with another card I had in it, so I know it's not totally dead).

Ideas? Got the card off of ebay, used, so I can't confirm it's a good card, but my best guess is that it's OK.

Running a W700, with Win7 64 bit.
