When trying to add a GoldMine Mobile license to a GoldMine Premium Edition Remote Site (S-License), get error: "You cannot change this Remote License. Please ask the Master License administrator to issue you a new Remote License."
this applies also to undocked user installations with a U-License. Here the user does not even have the possibility to add a further license or license type
The GoldMine Mobile License can only be entered on a GoldMine Premium Installation which is using the primary/master GMPE License Key. This is the license key which begins with the letter "E".
