SU2020 does the registration correctly for me on three different computers. Are you certain you installed SketchUp correctly?
The problem only occurs with a clean installation. If you have installed SU19 or SU19 + SU20 together or are doing an update, then there will be no problem. Keys will already be registered. Maybe my installer is broken, but other users have the same problem. Now there is a solution ...
