The error message says 'The fingerprint reader is not connected. The plugin installed correctly, however, it also gives me the same issue upon scanner Window launch. It comes with a sample FileMaker application for enrolling fingerprints and searching them. I tried the Biometric Fingerprint Plugin (by Productive Computing) for FileMaker and installed version 2.0.1.2. I tried switching the device driver from 'U.are.U 4500 Fingerprint Reader (WBF)' to the normal 'U.are.U 4500 Fingerprint Reader' but it didn't help.

The sample applications ran, but when the scanner window launches, it does not detect the connected fingerprint reader. I then installed the SDK on an older Windows 10 installation (64 bit, 1709 Build 16299). I checked the 'Remote Procedure Call' and 'DCOM Server Process Launcher' but they're already running. It gives the error: 'ERROR: The RPC Server is not listening (0x800706B3)'.

However, the SDK samples do not seem to work while launching the scanner window. I installed the DigitalPersona SDK 1.6.1 on my system (Windows 10 Pro 圆4, 1904 Build 18362). I'm currently working to integrate the DigitalPersona U.are.U 4500 Fingerprint Reader with our FileMaker application.
