The licenses you've ordered are provided by ~sedna in the Licenses section of Presenter Cloud, or as license dongles that you can connect to the USB interfaces of the corresponding Macs. If you use license dongles, you can run Presenter Player or Presenter Creator without any further registration procedures.
1. Run the application: If no dongle is found, a procedure is initiated during which you can register the individual installation on Presenter Cloud. Note that this requires an Internet connection. Click on the Cloud... button of this dialog. Another dialog will be prompted. Enter in this dialog: The ~sedna ID that you can find in the My Organization section of Presenter Cloud. The ~sedna Key that you can find at the same location. A name that will serve to identify the application instance. This identifier is displayed in Presenter Cloud.
2. Confirm the dialog: The application will go into stand-by mode to wait for the license assignment. If Presenter Cloud can't be reached, you can quit the Player (or Creator). Next time you start the Player, it will again continue to request a license until the Presenter Cloud server carries out the license assignment.
3. Assign License: This part is done in Presenter Cloud. As described in the Player section or the Creator section, look up the new instance in the Unassigned list. Select the corresponding entry and click on the corresponding button to assign the license.
4. Run the application: Eventually, the Player (or Creator) will receive the license. You may have to restart the software to start working with it.
