The following instructions are valid for Windows 7. Instructions may differ slightly for different versions of Windows, but the principle is the same. If in doubt, consult the operating system documentation.

Downloading VNC

Download the VNC for Windows executable to the computer you want to control. A single program installs both VNC Server and VNC Viewer.

Note: VNC Viewer is freely available to download to as many other computers that you wish to exercise control from as you like.

If your firewall blocks executables, download the VNC for Windows zip instead.

Installing VNC

Using desktop tools

Double-click the executable to start the Installation Wizard, and follow the instructions. Note the credentials of a user with administrative privileges on the computer are required.

At the command line

Installing at the command line may be quicker and more convenient providing defaults are acceptable. To do this:

  1. Open a Command Prompt. On Windows Vista and later, perform this operation as an administrator (right-click Start > All Programs > Accessories > Command Prompt and select Run as administrator), in order to suppress UAC prompts.
  2. Run the following command:
    By default, the following components are installed:
    • VNC Server.
    • VNC Viewer. To suppress installation, specify /COMPONENTS="WinVNC,WinVNC\VNCPrinter,WinVNC\VNCMirror"
    • VNC Mirror Driver. To suppress installation, specify /COMPONENTS="WinVNC,WinVNC\VNCPrinter,VNCViewer"
    • VNC Printer Driver. To suppress installation, specify /COMPONENTS="WinVNC,WinVNC\VNCMirror,VNCViewer"

Using VNC Deployment Tool

VNC Deployment Tool is freely available to simplify installation and configuration on multiple Windows computers over a network.

Licensing VNC Server

VNC Server must be licensed. If it is not, users cannot connect. More information…

Note: VNC Viewer does not require a license key.

Using desktop tools

To obtain and apply a license key, start VNC Server, open the VNC Server dialog, and either follow the instructions in the VNC Server is not licensed error, or select More > Licensing.

At the command line

Obtain a license key, and then run the following command as a user with administrative privileges:

<install dir>/vnclicense.exe -add <license key>
By default, <install dir> is C:\Program Files\RealVNC\VNC Server.

Removing VNC

To uninstall VNC Server, use Control Panel > Programs and Features in the standard way to remove the VNC Server program. Note the credentials of a user with administrative privileges on the computer are required. To uninstall VNC Viewer, repeat this operation for VNC Viewer.

The VNC Printer Driver and VNC Mirror Driver programs are automatically removed. You may need to restart the computer.
