How many licenses do I require?

VNC Enterprise Edition for Windows is composed of two components, VNC Viewer and VNC Server. VNC Server is installed on each host computer whose desktop is to be remotely accessed, and VNC Viewer is then run by each user who must access those computers.

Licensing for VNC Enterprise Edition for Windows is based on the number of copies of VNC Server that are to be used, i.e. the number of host desktops that are to be accessed remotely by users running VNC Viewer. Any number of VNC Viewers may remotely access a single VNC Server for personal or internal business use, under a single VNC Enterprise Edition for Windows license. The number of licenses required depends solely on the number of VNC Server installations.

How many license keys do I require?

Each VNC Enterprise Edition for Windows license key entitles the holder to install VNC Server Enterprise Edition on a specified number of host computers. If more VNC Server installations are required than are permitted with a particular license key, then supplemental license keys must be purchased.

The VNC Deployment Tool includes a no-fuss license auditing feature to help maintain your VNC Enterprise Edition licenses.

How long is my license valid for?

Each VNC Enterprise Edition for Windows license is perpetual, meaning that it can continue to be used with the original software for as long as is required.

How long is my basic support agreement valid for?

The basic support agreement, including free upgrades as they become available, runs for a period of 12 months from the date of issue of the accompanying license key. Upgrades released after this 12 month period has elapsed will not be available unless the basic support agreement has been renewed and a replacement license key issued.

How do I get a 30-day trial license?

During installation, VNC Enterprise Edition for Windows prompts for a license key. Enter a full license key if you have one. If you want a 30-day trial license, click the Trial License button.

You can click the Cancel button in this dialog to install without a license key. Before you can use the software, however, you must still unlock it. To do this after VNC Enterprise Edition for Windows has installed, select RealVNC > Advanced > Enter VNC Server License Key from the Start menu (under Windows XP).

How do I install a new license key?

During installation, VNC Enterprise Edition for Windows will prompt for a valid license key to be supplied, if a valid key is not already present on the host computer.

A license key must be installed on each computer that is to run an Enterprise Edition VNC Server; you do not need to install a license key on a computer that will only run VNC Viewer. A new license key can be installed even when the existing key is valid, for instance when replacing a 30-day trial license with a full license, by selecting RealVNC > Advanced > Enter VNC Server License Key from the Start menu (under Windows XP).

The newly installed license key will take effect immediately, for all new connections to VNC Server.
