Use this option to manually enter a registration or license key.
Select Register from the UPDD Daemon menu, as per this MacOS menu bar example:
then the 'Enter a license key' option:
A licence key, typically 13 digits long, can be used to convert a trial version of the driver to a full production version.
A license key represents an available license on our license server waiting to allocated to a system.
If the system is online the license will be approved and the software will be licensed.
If the system is offline it will enter an offline retrieval procedure and general a URL link which you enter into a browser on an online system. This will then return a Registration key that is entered into the above dialog on the offline system and the software will be licensed.
The offline order process is used to generate registration data for a system that is not connected to the internet. At the end of the offline procedure you will have generated a registration key that can be entered here on the target system. It can only be entered on the system used in the offline procedure.
