To provide a complete report on VNC Server licensing and serial numbers, it is important to understand that modern versions (specifically RealVNC Connect) have transitioned from traditional "serial keys" to account-based subscriptions. 1. Modern Licensing: RealVNC account

For most current subscriptions, you do not need a physical serial number or license key.

Method: Sign in to the VNC Server on the remote device using your RealVNC account credentials (email and password).

Automatic Activation: Once signed in, the server automatically detects your plan (e.g., Lite, Essentials, or Plus) and applies the license. 2. Legacy and Offline License Keys

If you are using an older version or an environment without internet access, you may still require a 25-character license key. | Error Message | Meaning | Solution |

Finding Offline Keys: You can find these details on the Deployment page of your RealVNC account portal.

Command Line Application: On Linux or Windows servers, you can often apply a key via the command line using the vnclicense utility (e.g., vnclicense -add YOUR-KEY-HERE). 3. Locating Server Hardware Serial Numbers

If your "report" requires the physical hardware serial number of the server where VNC is running, use these commands:

Windows: Open Command Prompt and run wmic bios get serialnumber. Linux: Run sudo dmidecode -s system-serial-number. 4. Common License Troubleshooting

Connection Refused: This often happens because the VNC Server service is not running. Check the status via RealVNC's troubleshooting guide or run systemctl status vncserver@:1 on Linux.

Subscription Per-User: Ensure that if your plan is per-user, you have also licensed the VNC Viewer on the device you are connecting from. Where is my license key? - RealVNC
