The Extrude Tools install and work just fine in all current versions of SketchUp.
So something is clearly wrong with your end...

Have you installed SketchUp properly ?
If you are using a MAC have you installed SketchUp properly - i.e. you NOT working from the installer app version...
But if you are on a PC Repair the installation whilst using Run as administrator on the Downloaded installer's exe file...

If all else fails, try this clunky work around...
Change the file-type suffix of the downloaded .RBZ to .ZIP
Now extract the contents to a folder and move the RB and subfolder of the same name [with its contents in tact] into your v2022 Plugins folder.

If it doesn't extract properly try downloading the RBZ another way...

After you get the RB & subfolder into Plugins restart SketchUp and see what happens...
