Updates are recommended for all Windows 10, 8, Windows 7, XP and Vista users. This blog post talk about most usual trigger for microsoft fingerprint reader driver issue, it's our lucky to help you fix this problem.
Killer Wireless 1535 Driver Windows 10 here. Yes, this product is no longer manufactured or supported by Microsoft, but, hey, it looks like a text-book scam. They launched the Fingerprint reader, advertised it like the next step in protecting your accounts and they launched drivers for x86 XP and Vista. No x64 support, no W7 support. It's common sense that they should support a product for a decent period of time, not for 2 yrs. I'm not buying hardware to use it just this year.
I'm not expecting to understand that, I just want to say that this issue really is annoying. I had installed ' in compatibility mode (Vista) on a W7 x86, the hardware is recognized, but don't want to register fingers (as it does flawlessly in vista x86). @Saginus: thanks for trying to help, but the only solution is a new working driver for W7, and for x64 OS as well. I know this hardware is discontinued, but his end of life was so soon.
