LibFredo6 glitch ... can't install Roundcorner

Tula Woodworking

First off, greetings! This is my first post. Here's my dilemma:

I installed LibFredo6 to install and run RoundCorner.
Despite this, I am continually prompted to install the LibFredo extension every time I open a SketchUp file on my desktop.
The Roundover extension will not install despite LibFredo being installed

I'm on a tight deadline to complete designs, and I'm pretty amazed at the extent of glitches. Any help would be appreciated!

Have you restarted SketchUp to sync everything ?

Have you installed the SketchUcation Tools needed for licensing ?

Assuming you are using Windows - have you installed Sketchup properly ?
Double-clicking the installer's exe file to 'Run' it is not enough, even if your user account has admin powers - doing so can cause unpredictable issues, often around permissions and file access.
It can be repaired without needing to re-install SketchUp - do the following...
It will leave any installed files etc unaffected...
Close SketchUp.
Find its installer exe file - usually in your Downloads folder [down load a new copy if you no longer have it].
Select the exe file's icon, right-click > context-menu > Run as administrator
When prompted choose Repair.
When it finishes restart SketchUp.

Any improvement ?
