Fingerprint reader not working

[burchland2]

I have a problem with my Lenovo B50-30 Touch with Windows 8.1 Pro. Every time I install the fingerprint reader for Windows 7 (because the one for Windows 8.1 does not seem to work), it says it couldn't detect the fingerprint sensor.What am I doing wrong here? Is there even a fingerprint sensor in my laptop at all?
