Update Activation Code

In the event that you receive a new license corresponding Activation Code, your activation code must be re-registered with Nessus.

You can update Nessus with the new activation code using either of the following methods:

  • Update the Nessus Activation Code in the UI.
  • Update the Nessus Activation Code via Command Line.

Note: If you are working with Nessus offline, see Register Nessus Offline.

Update Nessus in the UI

  1. In Nessus, select the button (System Settings page).
  2. Select the button next to the Activation Code.
  3. On the Update Activation screen, select your Registration type.
  4. Enter the new Activation Code.
  5. Select Save.

    Next, Nessus downloads and installs the Nessus engine and the latest Nessus plugins.
