I just decided to reinstall again the driver and there was ist...
After running the driver.exe file I get to choose:
- make changes to the software
- repair the software
- uninstall the software
I alwas reinstalled it. During the installation process I somehow did not find the checkmark "SketchUp".
By choosing "make changes to the software" I was able to select SketchUp, click ok and it was done...
Thanks a lot for your Support!!! Great!
