Code Example

        // The Device ID is optional, but if it is used and the license keys was activated with it
        // it becomes required, a license key activated with a Device ID can't be deactivated
        // without it and can't be activated again without it.
        // The device ID can be anything you want, its role is to identify the "Device",
        // "Machine" or "Domain" where the license was activated.
