Rhino 6 Will Not Open - Showing "Please Wait..." Window


Rhino recently crashed on me while working on a large (7GB) file on Windows PC. Now, after trying to open any file (even a blank file in SafeMode), the Rhino start-up window pops-up along with a loading bar that says “Please Wait…” which cycles endlessly, never opens a Rhino starting file, and then eventually disappears after 20 minutes.

Is there any way I can go about fixing this without uninstalling/re-installing (and presumably having to re-enter my license code)?

Thanks in advance for the help!

Check to see if you have any “Ghost Rhinos” still running in task manager… If so, you need to kill those.

Then, if that doesn’t help, I might try first to repair the Rhino install -
Go to Control panel>Programs>Uninstall/Change program, find Rhino 6 in the list, right click on it and select “Change”, then press the Repair button in the splash screen that comes up…

Problem solved! Thank you so much!
