Download and Copy License File (nessus.license)

After you have generated your Nessus license, you now need to download and then copy the license to the offline system (A) running Nessus.

  1. At the Nessus Offline Registration Page, while still using the computer with internet access (B), select the on-screen nessus.license link.
    The link will download the nessus.license file.
  2. Copy the nessus.license file to the offline system (A) running Nessus 6.3 and newer.

    Use the directory specific to your operating system:

    Platform

    Directory

    Linux

    # /opt/nessus/etc/nessus/

    FreeBSD

    # /usr/local/nessus/etc/nessus

    Mac OS X

    # /Library/Nessus/run/etc/nessus

    Windows

    C:\ProgramData\Tenable\Nessus\conf

  3. Next, register your license with Nessus.
