The first place to look to see if the driver for MFS100 Fingerprint Sensor was actually installed is the the Device Manager. Press Windows Key + R and type devmgmt.msc. There shouldn't be anything marked with a yellow or red sign. If there is something with yellow, it means the driver didn't succeed installing properly and you should try again, but this time use the correct one.
Also, it might be possible that the driver you are trying to install is not compatible with the operating system that's currently running on your PC.
