Be sure you've already installed SketchUp Pro.
On MacOS, go to the Applications folder and open the SketchUp folder with the year’s version you want to open. Open the SketchUp or Layout application within that folder.
On Windows, SketchUp should have created shortcuts on your desktop, but you can also open it from C:\Program Files\SketchUp\SketchUp 2020 (or another year’s version number) by double-clicking on the program file.
