Try repairing your redistributables.

If you can open in safe mode please run the SystemInfo command.

Rhino 8 won't open

Hi Teigan, Does Rhino open in safe mode? (search for Rhino 8 in safe mode in the windows start) If it does please run SystemInfo in the command line and post the results. There were a few people that had issues with recent windows updates. Try repairing your Microsoft redistributables [image]
