When you install the PRO version, the Joomla dashboard shows a message that a download key is missing.

Since QR Code 6.2.0 and version 5.4.0 of the other four plugins, the same reminder appears as a red message above the edit screen of a field, for as long as no key has been entered. That message also tells you when your license is about to expire or has expired. Only administrators who are allowed to manage extensions see it.

You need this Download Key to enable automatic updates for our extensions. Our system checks that the key is valid and that your subscription is active.

You can find your personal Download Key on our website:

Copy the Download Key and paste it into the Edit Update Site screen.

When you're done, press Save & Close.
