When you purchase a licence to use Keyman Desktop, you can enter the licence into the free version of Keyman Desktop. This will convert the free version into the fully licensed Professional version.
The simple answer is that each licensed seat of Keyman Desktop is for a single computer. When you purchase Keyman Desktop, you will find a 'seat count' included in the licence details. A standard licence includes one seat, which should be used on one computer. If more than one person uses the same computer, you still only need a single licence - except in Citrix, Terminal Services, or similar environments.
The fuller answer is that Keyman Desktop licences are per concurrent-user seat (like MS Office). For systems running Citrix, Terminal Services, or similar software to enable concurrent use of Keyman by multiple users on the same computer, the number of licensed seats defines the maximum number of permitted concurrent users.
You can move a licence to another computer, even after you have activated Keyman Desktop, by contacting Tavultesoft Support (firstname.lastname@example.org) with your licence details and a note about moving the licence and the reason for the move (for example, purchasing a new computer, or replacing a computer that had a hardware failure). You must also uninstall Keyman Desktop from your original computer.
