problems with cudadriver 2.2 for win 7-64 (185.85)

I have not been able to run the cudadriver_2.2_win7_64_185.85_general driver successfully. I get an error which says that the driver does not detect 64bit win 7 drivers/hardware. I then get an error message that says the uninstaller is win32, and will not run on a win64 system.

Any ideas?

I have anintel core i7 860 CPU, 4 GB ram, and am running Win 7 64 bit.
