Configuration Utility and server

I tried to install the WM-Bridge service on Windows 10 64bit.
The Config-Tools reported a program error - but after that followed the message: service successfully installed...

Now I can see, that the WMBridge service exists, but I cannot start it. Here the Windows error message:

Der Dienst kann nicht gestartet werden. System.Reflection.TargetInvocationException: Ein Aufrufziel hat einen Ausnahmefehler verursacht. ---> System.Net.HttpListenerException: Zugriff verweigert

Any ideas?
