Installing and removing VNC Connect

These instructions explain how to install VNC Connect (version 6.x) on principal Windows computers.

Note

Separate MSI installers are available for VNC Server and VNC Viewer to facilitate remote deployment to multiple Windows computers using industry-standard tools such as Group Policy.

Upgrading to VNC Connect

If you are upgrading from VNC 5.x and have a valid Personal or Enterprise license key, installation should be seamless. You do not need to stop VNC Server, and any configuration changes you have made will be preserved. If you wish to enable cloud connectivity, perform this post-install step.

If you have an out-of-date Personal or Enterprise license key for VNC 5.x, you must purchase a subscription as a new customer.

If you have a Free license key for VNC 5.x, you can migrate to a new, free Home subscription providing you install VNC Connect desk-side. You cannot migrate over a remote control session.

If you wish to upgrade from VNC Enterprise Edition or VNC Personal Edition 4.x, we recommend you first contact Support.

Downloading VNC Connect

Download the VNC Connect executable to the computer you want to control. If your firewall blocks executables, download the zip archive instead.

Note

VNC Viewer is freely available to download as a separate app to devices you want to control from.

Installing VNC Connect

Under Windows 8 or later, it is recommended you install to a secure location (for example, C:\Program Files).

Using desktop tools

Double-click the executable to start the graphical Install Wizard, and follow the instructions. Administrative privileges are required.

At the command line

Installing at the command line without prompting the user or restarting the computer may be quicker and more convenient:

  1. Open a Command Prompt. On Vista and later, perform this operation as an administrator (right-click Start > All Programs > Accessories > Command Prompt and select Run as administrator) to suppress UAC prompts.

  2. Run the following command:

    <VNC>.exe [/VERYSILENT] [/NORESTART] [/SERVERARGS ENABLEAUTOUPDATECHECKS=0|1|2]

    By default, the following components are installed:

    • VNC Server. To suppress installation, specify /NOSERVER.
    • VNC Viewer. To add a desktop shortcut icon, specify /VIEWERARGS ADDLOCAL=ALL. To suppress installation, specify /NOVIEWER.
    • VNC Mirror Driver (Windows 7 and earlier). To suppress installation on these platforms, specify /NOMIRRORDRIVER.
    • VNC Printer Driver. To suppress installation, specify /NOPRINTERDRIVER.

Licensing VNC Server

You must apply a subscription to VNC Server. If you do not, remote access will not be available.

Note

VNC Viewer does not need to be licensed.

Using desktop tools

Open the VNC Server dialog and select Licensing from the menu to open the graphical License Wizard. Follow the instructions to sign in with your RealVNC account credentials.

If you have an Enterprise subscription, direct connectivity will be automatically enabled, and you are prompted to enable cloud connectivity at the same time.

At the command line

Note

You can only license VNC Server at the command line if you have an Enterprise subscription.

A 25 character license key for offline or remote deployment is available from the Computers page of your RealVNC account. To apply it, 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.

Direct connectivity is automatically enabled. To enable cloud connectivity, run the following command as a user with administrative privileges:

<install-dir>/vncserver.exe -service -joinCloud <registration-token>

Registration tokens are also available from the Computers page of your RealVNC account.

Starting VNC Server

VNC Server starts automatically in Service Mode.

To learn how to operate VNC Server at the command line, see this page.

Changing or repairing VNC Connect

You can change or repair VNC Server or VNC Viewer using Control Panel > Programs and Features in the standard way.

Removing VNC Connect

You can uninstall VNC Server or VNC Viewer using Control Panel > Programs and Features in the standard way. Administrative privileges are required. You may need to restart the computer.
