I just installed FreeCad from the AppImage Package!
I went here and read about the AppImage packages:
https://www.freecadweb.org/wiki/Download
Then I went here and downloaded the latest 0.17 AppImage file:
https://github.com/FreeCAD/FreeCAD/releases
Then here to find out how to run it (The "How to run an AppImage?" video :
https://appimage.org/
Then I simply added the command to the start menu, under "Grafic"
And at last I have a working FreeCad on my system
