To transfer your subscription to a different PC, there are two different methods:
Logging Out from Dante Studio
Logging out of the Dante Studio UI will deactivate your license on that PC.
Restoring the License on the web interface
Alternatively, if you do not have access to the PC or Dante Studio UI, you can recover the license by following the steps here.
In both cases, on logging into Dante Studio on another PC, the license will automatically be transferred.
