VNC (excellent remote access/control software tool) of which I use the RealVNC variant (http://www.realvnc.com/) does not work (in ver 4.1.2) straight out of the box under Vista. Basically the services just don’t install correctly. I’ve fixed it for my x64 machine, it’s so simple and obvious:
1) Run VNC installation
2) Untick Register and configure VNC Server for Service-mode
3) Untick Start the VNC Server in Service-mode
Now copy your
Programs > RealVNC > VNC Server 4 (User-mode) > Run VNC Server
Shortcut into your Programs > Startup folder and it’s a bit like running it as a service (or rather from outward appearances you’d never know the difference).
Don’t forget to run the program once (or restart) and unblock the app in Windows Firewall.
Here’s the Wiki on VNC, if you have multiple pcs and hate walking between them, or you’re an IT admin, you should already know what this is
