Once you possess a valid 25-character enterprise key, you can activate the VNC Server without an internet connection using two primary methods. Method 1: Using the Graphical User Interface (GUI) Open the application on the host machine. Click the menu icon (three lines) and select Licensing . Choose the option to Enter a license key directly . Paste your 25-character key into the field. Click Next to complete the offline activation. Method 2: Using the Command Line (CLI)

When you use an offline license, your data traffic does not pass through RealVNC’s cloud servers. Instead, connectivity relies on via a local area network (LAN), VPN, or direct public IP routing.
Remote access is a critical capability for modern IT management, but not every environment is connected to the cloud. Air-gapped networks, highly secure data centers, and remote facilities often require a solution that works entirely offline. For these scenarios, RealVNC offers a powerful alternative: the offline license. Once you possess a valid 25-character enterprise key,
Transfer the license.rlf file back to the offline machine (via USB).
While cloud-based licensing is convenient for many organizations, stringent security policies (government, defense, finance, or critical infrastructure) often require complete network isolation. For these "air-gapped" environments, is essential. Choose the option to Enter a license key directly
