Finally got this working correctly in Windows 7 64bit without having to purchase software. The standard windows driver (once you remove and update the Authentec AES 2550 driver via the device manager) does not provide a password bank for IE8, or Firefox.
This T4410 has the P8700 chip, 4GB of RAM, Windows 7 64bit and an Intel 128GB 25nm SSD drive. It zings along quite nicely with a read spead of 200MB/s and write speed of 100MB/s to the SSD. The thumbprint scanner is something I've become to rely on (mostly UPEK via USB) to keep strong passwords stored for various web based applications.
So after a few hours of messing around, here's what worked:
1. Remove the Windows 7 driver for the Authentec AES2550 (Device Manager) and allow it to install automatically via Windows update.
2. Uninstall anything (using the Add/Remove Programs control panel application) that refers to Truesuite, or Authentic software. Reboot.
3. Install the Vitakey software from here: http://www.egistec.com/download/update-vitakey5.aspx
Reboot. You'll need to set up the software via the EgisTec program group (System setup app) from your Start Menu.
4. The driver version for Authentec AES2550 from windows device manager should read 18.104.22.168. I couldn't get the software working with any other version of the driver. Windows update seems to have an older driver..so don't update the driver via Windows Update.
Now you'll be able to log in to windows with a scan. Also, when you visit a password protected site via IE8, the Vitakey applet will pop up to ask if you wish to save the password. From there on in, it's just a matter of scanning a print to get access. This does not work with Firefox at all which is the one downside to this setup.
Hope this helps.
