Upgrade from Evaluation
If you used an evaluation version of Nessus and are now upgrading to a full-licensed version of Nessus, you simply need to type your full-version Activation Code on the Settings page, on the About tab.
Update the Activation Code
- Select the button next to the Activation Code.
- In the Registration box, select your Nessus type.
- In the Activation Code box, type your new Activation Code.
Nessus downloads and install the Nessus engine and the latest Nessus plugins, and then restarts.
