installing the arduino with windows vista

Hello,
Trying to install the arduino software...umm not that easy. Is there a link with a complete installation procedure maybe with a printable list of setup i need. it’s definitely not plug and play .
I’m using windows vista and arduino uno. When i click on the window installation from arduino.com i get a file a rar format.....after that i have no clue what to do.
thank

I have Vista. All I've ever done was download the file

Unzip it
and run the arduino.exe.

Drivers, point windows at the c://arduino-1.0.3/drivers folder or whatever path you use.

i did load a few sketch...working now thanks
