Hi!
I have Dell Vostro 5470 laptop, with installed Windows 8.1 Professional 64-bit.
I have installed Fingerprint Driver and DigitalPersona 6.2 update, in different sequence, but still - the reader is visible at Device Manager, but NOT visible for Windows Fingerprint login or DigitalPersona.
I have searched and tried different solutions (including Fingerprint sensor drivers etc.).
Still no luck. And this seems to be some Driver issue from dell (latest sensor driver is y2013, and there are few forum threads still without solution).
