I have an ENVY dv6-7247cl HP Laptop Computer. Warranty is over. Having issues with Simple Pass fingerprint sensor. I've tried uninstalling and reinstalling the Simple Pass Driver and Validity Sensor several times to no avail. I had problems with my Norton Security software which has since been resolved but in doing so, somehow affected my biometric reader. I am not tech savvy by any means. The validity sensor said something about about a missing or damaged registry which is why I did the uninstall/reinstall. It says the device is working properly but apparently not since I can't set-up Simple Pass to even enroll any fingers. It keeps asking me to try again after I "Left Click" on the finger I want to enroll but they keep saying there is an error but never say what the error is or how to resolve it. PLEASE HELP! I bought this laptop specifically for the biometric reader. --Thanks in advance
