Is the PlanetCNC software license transferable?

Looking at buying a secondhand Mk 3/4 board and need to know if the license for the software that is being offered with it is transferable to me?

Thanks!

If controller has license (you get existing license from seller) then you can use it.
If you do not get licence with controller then you need new one.

Outstanding, thanks very much!

Just confirming for anyone coming along later: the license installation went perfectly and the hardware and software are working as they should.
