To access the Edit License Key dialog:
Select a license server, click the button in the Toolbar or right-click and select the Configuration command, then click the Licenses tab. Select an existing license key and click the Edit button.
The Edit License Key dialog lets you enable and disable soft licenses for this key. Note that, to change a license key, such as to convert a license from evaluation mode to licensed mode, you must remove the previous key and add a new one.
