I have some troubles with fingerprint software. I already installed device driver and windows_wbf_tek_4_3_34_0_digital_persona_fma. at now time i see button "manage your fingerprint data" in Control Panel\All Control Panel Items\User Accounts but when I push it I recieve a message "there are now fingerprint readers available at this time." In Device manager I see "Biometric Device"->"Validity sensor". How can I resolve this issue?
