Quickstart
Before installing, keep this setup on a trusted network. On an untrusted network, establish a tunnel first. See TightVNC FAQ and the Security and remote access best practices guide.
The installation documents describe versions 2.6 and 2.7.
- Install the TightVNC MSI on the computer you want to access. Administrator rights are required. Leave service registration selected to register and start TightVNC Server.
- If the server refuses the connection, first check that a Primary or View-only password is set. With authentication enabled and neither password set, TightVNC 2.8.88 rejects incoming connections.
