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.
