Installing and Removing VNC Connect


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

VNC Connect consists of a VNC Server app for the remote computer you want to control, and a VNC Viewer app for the local device you want to control from.

*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 from legacy versions

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,enable it by selecting Allow cloud connections in the VNC Server Options dialog or set the AllowCloudRfb parameter.

If you have an out-of-date Personal or Enterprise license key for VNC 5.x, you must purchase a subscription as a new customer.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

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