Hi, I just installed Rhino 6 for Windows (Educational Version) on a 2011 MacBook pro running Windows 8.1 with BootCamp; right after the installation the .gh, .gha and 3dmbak icons have disappeared leaving the same icon you can see in the picture. Looking into each file Properties, they are seen as GH File (.gh), GHA File (.gha) and 3DMBAK File (.3dmbak) respectively.
So far I have (unsuccesfully) tried the same solutions suggested here:
also from this old post: http://www.grasshopper3d.com/forum/topics/how-to-make-computer-recognize-gh-files-aka-bring-back-gh-icons1
I have tried (as suggested in both of the discussion linked above) to delete the .gh .gha and .3dmbak entries in
Closing all explorer windows before, then killing explorer from the task manager and starting it again as a new task, but somehow those extensions are immediately recreated.
I’d really appreciate if someone has found a solution to this nuisance and is willing to share it!
