hey Tig, The issue was with LibFredo6, I had to download & install version 14.8, I assumed that the version of Libfredo6 that was installed was upto date & correct.
Thanks for your responses.

Thanks Tig, Ye I had restarted to no avail.

Hello, Can you help?
I run Sketchup Pro 2024.
I have SketchUcation latest version.
I have LibFredo6 latest version.
Upgraded to licenced version Fredo6 ThruPaint 2.8a.
ThruPaint shows in my Sketchup extension manager, shows in SketchUcation extension manager, shows that it is licenced, but I can not find or use the extension in Sketchup Tools or Extensions.
Where is it hiding?
Any help would be much appreciated.
Many Thanks
Sean P.
