A fixed-seat license is limited to one machine. To transfer it, use the Remove function in the General Settings menu.
A floating license can be used on multiple machines, as long as the number of opened Enscape windows does not exceed the number of licenses. An internet connection is required, but no additional manager. If there is no internet connection while you try to open Enscape, Enscape will start a 24 hour timeframe, counted on from the last successful validation. During this timeframe, you will be able to use Enscape as usual. If your computer still has no connection after 24 hours, or if your computer regains internet connection, but all of your seats are currently being used, Enscape will get watermarked.
