It seems that I need to download LibFreido6 and upgrade it. Nothing I download with run and install program, it just takes me to Sketchup home screen. If I go into extension Manager there seem to be no place for me to run the update

@Rich-O-Brien
When I download the file and open it then It takes me directly to the front page of Sketchup. I can find no place with Sketchup to run the file It is downloading 4.4.1, is this correct

I downloaded round corner trial and loved it so I purchased the $50.00 package assuming that it would update the expiry on the trial version. Today I discovered that it did not update. I can not figure out how to upgrade the plugin. When I run the download it simply takes me to the Sketchup start screen from there I have tried to do many things with no success.
Please help me.
