Do I still need a license key?

Not if you have a Home or Professional subscription. Signing in to VNC Server desk-side at install-time automatically applies your subscription to that computer.

If you have an Enterprise subscription, you have a little more flexibility. A 25 character license key is available on the Deployment page of your RealVNC account. This key is:

  • Useful if you wish to license VNC Server in bulk or remotely, for example using policy.
  • Mandatory if the remote computer is not connected to the Internet.

To apply a license key, run the appropriate command as an administrator:

  • Windows:
    vnclicense.exe -add XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
  • Mac:
    sudo /Library/vnc/vnclicense -add XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
  • Linux:
    sudo vnclicense -add XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
