I just had EE (driver version is 5,2,10,6) installed on my ThinkPad T420.
Prior to the install, the FPR was working fine. Now, when I try to run ThinkVantage Fingerprint Software (v18.104.22.16838) (a.k.a., "Lenovo - Fingerprint Reader" in Control Panel), I get an error "An internal error occurred (rpnp2: no-svr(00000001fusserver))." When I close the error dialog, the ThinkVantage Fingerprint Software application runs, but it doesn't show any available FPR and won't let me do anything.
Without the config software, I'm unable to enroll fingerprints, etc.
