I am using Sketchup 2024 Pro version on a PC computer.
I have downloaded LibFredo6-v14.5f:
- 
the logo appears in Extension Manager but only as a grey (ghost) logo
 - 
does NOT appear in Extension Warehouse
 
I have viewed the 15 minute video several times and still cannot figure out how to get access to the App. the video covers so many topics.
Is there a simple set by step guide - text or video that show how to install LibFredo6?
