Vue should install no problem, if you use desktop shortcuts be sure to right click and under properties there is a tick box to run as administartor, make sure it's ticked! The tick box is a recent addition in one of the latest updates to Vista!

make sure you have all the updates from Vista, there are some major improvements to what you might get in the box!
Turn off the UAC if you're comfortable doing that, you'll quickly get fed up of the nag screen each time you want to do even a simple task like moving a folder or something!

Vista takes some getting used to but once you're there, IMO it's a good OS!

Injustice will be avenged.
