As a solution I treid the workaround through the "cmd" to start the service. Here is the result:
"Assertion failed: Operation timed out <......\src\signaler.cpp:160>"
This was the answer of the supportdesk on the issue:
*That's an error in libxs (Crossroads) that we have not seen before. At least we're getting closer to understanding the problem.
With some effort there are a few things we could do to get debugging info deep in that library.
In the meantime, the first easy thing to check that comes to mind is that you may have another program using port 5905 (signaling port for libxs) which conflicts. (VNCServer is one known possibility given it starts consuming ports at 5901.) If you download and run TCPView (a pretty small and useful diagnostic tool) do you see any other programs using port 5905?*
Well I tried that one as well and my answer was:
Port 5905 isn’t used on my computer.
And then it went silent. Can you help me out? I just tried the controller on my wifes Windows 7 Laptop and it worked, but it doesn't work both my Windows 8.1 Desktop and Laptop.
I'm using Avast Internet Security which does'nt block Leapmotion.
