Have you tried the 'click here...' link on the dialog ?
Have you tried it with the Ruby Console open, are there any messages there ?

When you installed SketchUp did you do it correctly ?
Close SketchUp if it's open...**happy wheels**
Select its installer's exe file icon [usually in your Downloads folder ?]
Right-click > context-menu > 'Run as administrator'
When prompted choose 'Repair'
This will ensure all of SketchUp's permissions are set up properly.
Nothing else will be affected.

Any better ?

Because the dialog uses Internet-Explorer [legacy] on PCs you should also clear your cache [Edge ?] and retry...

I have the same questions. Did you resolve it?
