After activating the application, you can add a reserve main license key and, if necessary, an active and reserve key for additional functionality. The procedures for adding a reserve main key and keys for additional functionality are the same.
To add a reserve main key or keys for additional functionality to the application:
In the lower part of the main window, click the area that displays information about the license and the key.

If you want to add a key using a key file, click the Select a key file link to open the file selection window that window, select the file with the .key extension.
If you add a main license key and the application is already activated, the new key is added as a reserve main key.
If you add a separate key for additional functionality, it is added as active unless a key for this additional functionality has previously been added to the application. A new key for additional functionality is added as a reserve key if a key for that additional functionality has already been added to the application.
If both an active key and a reserve key were previously added to the application, the new key replaces the previously added reserve key.
A trial license key and a subscription key cannot be added as a reserve key.
