Rhino 6.22 - missing library icons

If your V6 or V7 WIP are not displaying material previews, run “TestRestoreLibraryFileAssociations” in the Windows V7 WIP, and it should re-register the thumbnail previewer dll for both V6 and V7.

It worked like magic! :trophy: :clap:

I like magic.

What I don’t understand is the sequence of events that requires to DLL to be re-registered.
