I then discovered that in my logon screen I had to click 'Switch User' and then my fingerprint logon appeared. I enrolled my finger-prints but even though I selected to use the fingerprint login in Windows it did not appear on my log-on screen. I installed it and lo-and behold Windows now told me that I had a biometric device. This morning in my Windows Update there was a new driver from AuthenTec. I then spent 2 hours on the phone with a Dell technician who basically went through everything again but this had no effect. Occassionaly I was able to install the DigiPersona software but it was unable to detect the finger-print reader. When I looked at the device manager it was there and working but Windows could not find a biometic device. I uninstalled everything again and then used Windows update to find a driver but in no case was Windows 7 able to detect the fingerprint reader. I tried numerous things such as uninstalling the AuthenTec driver, uninstalling the DigiPersonal fingerprint software then reinstalling from my original Vista disks.
