I've been running Windows 7 Professional on my Lenovo Thinkpad W500 for a long time. I used Lenovo's fingerprint reader software to enroll my prints and to log on to Windows.
Recently I reinstalled the operating system and all goes well when I enroll prints, but the enrollments do not save. Next time I boot and/or run the Lenovo fingerprint software there are no enrollments.
Complete removal and reinstallation of the fingerprint software has no effect.
Windows 7 has SP1 and is otherwise up to date on all critical updates. Lenovo software is latest.
How can I troubleshoot?
