To transfer licenses from one machine to another you need to free up (remove) your activation on the licensed machine. You may do this
by deactivating the registration from within the KillDisk application:
Start registration wizard
Click Registration menu item from Help menu.
Select deactivate option
Select the Deactivate Registration radio button. Click Next to proceed with the
registration.
Deactivate registration
Click Deactivate Registration button to complete online license deactivation.
Click Next and Finish buttons to confirm and close registration wizard.
Your active license is now revoked from your PC and may be used to activate a different computer.
Note: Uninstalling the application
from the computer using the uninstaller will also deactivate your license.
