You have to insert your own user-name into the path !
C:/Users/YOUR_USER_NAME/AppData/Local/LIBFREDO6_DATA_Dir

Then restart SketchUp..."

Right, did that, did not fix it.

"Close SketchUp and find and delete the following subfolder...
C:/Users/S155785/AppData/Local/LIBFREDO6_DATA_Dir"

Didn't work. Now what? TIA.
