I've got a Studio 1537 and the Authen Tec Inc AES2810 fingerprint reader has stopped working.  The problem started when the system's Software Update offered an update (from 4.x to 5.x).  At the end of the install I got an error message about a particular file was "not marked for install".  After that I got a message that the fingerprint reader was "not detected".  I have uninstalled both the software and the driver about 10 times to no avail. Went back to the original 3.x software version from install disks provided when I bought the computer, then upgraded from there to the latest version (checking along the way, but now luck).  I let windows find the driver from Windows Update, I've downloaded the driver from the manufacturer, etc.  Deleted the device and let windows find it again...tried every version of the driver I could find.  Nothing seems to connect the software with the hardware, yet device manager reports that the device is "working properly". 

This system came with Windows Vista and I upgraded about a year and a half ago to Windows 7 Ultimate.  Been working fine ever since (until this upgrade episode). 

Any thoughts? 

Thanks.
