Thumbnails missing after Rhino 6 deinstallation


a customer noted he has installed Rhino 5, Rhino 6, and Rhino 7. After deinstalling Rhino 6 the Windows thumbnails preview for 3dm-files is missing.

What to check?



Hi Michael -
I would try a repair of the Rhino 7 installation before anything else.

Hi Wim,

yes, repairing fixes the problem. I found also, installing the latest service Release of Rhino 7 fixes the problem.

I have written a small “How to fix thumbnail problems” in my forum:,9118

Thank you very much and a sunny Wednesday
