Cannot uninstall the plugin

Hi,
I downloaded a plugin and was in a rush. I I didn’t place it in plugin files. I installed it while it was on the desktop. So I guess I’m paying the price now. Sketchup cannot uninstall it, I tried to deleting plugin from desktop but this didn’t delete it from extension manager. I downloaded it again and placed it in right place (Local Disk (C:)/Users/“User Name”/Appdata/Roaming/Sketchup/Sketchup 2021/Sketchup/Plugins) and then installed in extension manager. But still uninstall button is grey. What should I do?

What happens if you download it again to the place you originally did?

If that doesn’t work, what happens if you try to reinstall?

Adding with Extension Manager would have been the normal way to install it, unless you were to get it straight from Extension Warehouse.

Try closing SketchUp, going to %AppData%\SketchUp\SketchUp 2021\SketchUp\Plugins and deleting the su_bezier folder and the su_bezier.rb file. Now open SketchUp and use Extension Manager to install the su_bezier_110.rbz file that you downloaded.

Thank you. That solved the problem.
