Vista - AuthenTec AES2810 fingerprint reader issue after fresh load of Vista x64

On my Dell Studio 1735 laptop I have been running with Vista Ultimate x32 since I got it - yes - the <gasp> factory load!

Everything worked flawlessly under that factory load.

I decided yesterday to install Vista Ultimate x64 after having downloaded all drivers from Dell's website that I needed (made sure to download the x64 specific drivers).

After installing, all drivers went in normally, but, the fingerprint reader (even though it's recognized in the control panel and services for it are running) doesn't give me the option of using it to logon to Windows or into any websites or anything else.

I tried removing and reinstalling the drivers - no change.

There is no GUI to enable/disable it that I can find. I've gone through the Program Files folder that it's installed into but nothing showing as an executable.

Anyone have any helpful insight?

Thanks in advance!

Update: I went through and installed from the ground-up again using the Driver Install Order for desktops and Laptops document on Dell's website... Still no change - can't get the fingerprinter reader to do much of anything other than install and services start.
