Returning a GeoStudio license makes it available for activation on another computer. Before returning the license, you will need to ensure you have an internet connection.
Launch GeoStudio and choose the Help | License Management menu option.
Then select Available Licenses from the pane on the left. You will now see a list of activated GeoStudio licenses on this computer.
To return a license, select one from the list and click on the Return button.
Once the license has been returned, it is available for re-activation on another computer.
