Hello Duane,
You will always get the edition selection screen when running Hauptwerk without a license, so there is no way around that and you must always choose the edition you wish to load. If you mean after that that you want Hauptwerk to automatically load an organ, that is done under General settings | General preferences then change the option for 'Load organ when Hauptwerk starts?' This can be done in the Basic Edition as well as the other editions. This is also covered in the main Hauptwerk user guide on page 133.
