Register Your License with Nessus

When you receive a new license and Activation Code, you must re-register the license with Nessus.

When your Nessus server is offline, you must generate a license, download the license, and then register your license with Nessus.

Once downloaded and copied to your offline Nessus server, use the nessuscli fetch -- register command that corresponds to your operating system.

  1. On the offline system running Nessus (A), open a command prompt.
  2. Use the nessuscli fetch --register-offline command specific to your operating system.
  3. Platform Command
