Installing and removing VNC Connect¶
These instructions explain how to install VNC Connect (version 6+), consisting of VNC Server and supporting platforms, on principal Windows computers you are licensed to control.
You are free to download VNC Viewer to as many devices you want to control from as you like, on any platform.
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If you have an out-of-date Personal or Enterprise license key for VNC 5.x, you must purchase a subscription as a new customer.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.
