The file contains hardcoded timestamp data. It remains valid until your current subscription period ends.
Ensure your offline license covers the specific number of "desktops" or "servers" allowed by your plan, as exceeding this will prevent the license from validating.
Offline licensing isn't just for convenience; it’s a requirement for specific network topologies: Air-Gapped Systems: Linux Deployment This method is ideal for Linux
between Linux and Windows.
Standard RealVNC subscriptions are cloud‑based: you sign into your RealVNC account on each device, and the license is automatically verified online. RealVNC Viewer and RealVNC Server must be connected to the internet at least periodically. This is suitable for most corporate, educational, and personal remote‑access scenarios where internet connectivity is reliable.
