SketchUp license install -- not showing on my computer

I just downloaded SketchUp Make for the first time. I’m supposed to activate a license, but don’t know how. Can I use the program, as a sole user on one computer, without a license ?

Thanks ! SDR

The Make version is free - it doesn’t need a license for that. The Pro version require a license - for which you have to buy one.

Thanks, Thomas. That gets me started !
