However, if you install the latest version 2.9.8 then you should not get that message any more as I removed that check. If you do have version 2.9.8 it means that you have an older version of TT_Lib loading, which would be a result of files in Virtual Store.

That was it! After changing my TT_Lib on 2.9.8 all things just works fine. But I've also change my permissions first.

Thank you soooooo much

Hello!
Need some help here please!
I downloaded TT_Lib2 and TT_QuadFaceTools, unpack them and put in my plugin folder. But when I start SketchUp it came with:
"TT_Lib2 detected that some of the files in plugins directory has ended up in Windows Virtual store. It happens because of insufficient permission for the plugin folder. Please move the files into the real Plugins folder."
