When you click the "Remove Software License" button the Configurator will disable the software and automatically attempt to notify our licensing server that the serial number is no longer in use. This allows you re-use the serial number to activate another installation of Robo-FTP.
If the Configurator is unable to reach our licensing server then a 24-digit removal code will be displayed on the License menu along with a button to copy the value to the Windows clipboard. You should keep a copy of the removal code so you can re-activate Robo-FTP with the same serial number at a later date.
