You may need this info on running 32bit application in 64bit environment...that seems to be why the driver is failing.

No I'm afraid not. It did not work. :( I guess it's just that win 7 is to new for this old fingerprint reader. :( I guess it's okay. I can always buy a usb fingerprint reader. Thank you all for the help. And if for some reason someone on here has the same model laptop and they have the same OS edition as me, and you got it to work please let me know how. Step by step please. Anyways, thank you all again I really appreciate the help.
