Rhino 8 installer leaves an empty WIP folder on PC

Folder named “Rhino 8 WIP” with same timestamp as “Rhino 8” folder. Folder empty apart from empty sub-folder “System”.

In addition to the empty System folder, mine also has a “Plug-ins” folder that has one item in it - digitize_MicroScribe.rhp.stop - but yes, all the rest is empty. I think you can safely delete it…
