I have tried everything that i could think of:
Uninstalled everything and reinstal
Checked add-on manager
Run the installer in repair mode
Installed BIMx viewer separately
Run as administrator
...
But i can't even find the problem, it just won't open.
When i save a file as a BIMx file and check the box start BIMx after save; nothing happens. Same thing when i just run the app or BIMx viewer.
