Hello guys,
The problem is resolved.
Download from here FSUIPC http://forum.simflight.com/topic/66139-updated-modules/
Install FSUIPC 4.81 first then copy the 4.812 dll to the FSX modules folder.
You should run FSX when you installing FSUIPC.
Then you closed FSX en restart FSX.
There went wrong.
Good luck and thanks for all your help.
Best regards,
Michael
