SketchUp is not resisting your installing Twilight Render Pro 2024 because it is a standalone executable installer. (Ie, it does not use SketchUp’s Extension Manager to install.)
Just go here: 2024 and the Twilight Render Sunset (post 2) - Twilight Render User Forum
… download the (Windows only) installer and run it with SketchUp closed.
Note: It will only work for SketchUp 2024 (using Ruby 3.2) and will not work for older SketchUp versions.
