I have upgraded by Studio 1735 from Windows 7 Ultimate (with DigitalPersona 5.3) to Windows 8 Pro.
The driver for the Authentec AES2810 is present in Device Manager (and the device works e.g. with Authentec TrueSuite Starter Edition).
I have installed DigitalPersona 6.2.1.309a (from http://support.dell.com/support/topics/global.aspx/support/kcs/document?docid=575108, I got the link to https://s3.amazonaws.com/flexnetconnect/dell/personal6.2.1.309/x86/setup.exe), it runs fine... but says it cannot detect the fingerprint reader.
Installing the Dell R207052 driver I had under Windows 7 doesn't help -- and Windows 8 upgrades the driver to the latest version anyway.
Any clue?
