Now the problem is solved so far. Got admin rights, but what I probably have doen wrong is simconnect.xml.
I don't know why, but i had changes the port in that file to 10747. Not standard 29674 which it should be.
A week vacation and fresh eyes helped.
Now I have minor adjustmenst left to get it to work Perfect.
problems still to fix:
-Scenery seems to move very quick (Ground speed 11 kts looks like 100 kts)
-There is flames from the Aircraft all the time
-Button inputs in PSX affects P3D. (If I raise gir, then view changes in P3D to spot view)
Thank you again for Your effort in helping me. I will continue to search for sollutions to get everything Perfect and give feedback if I find ways to fix it.
