A friend bought a script that we are going to use at a site we're going to open, and she forwarded it to me for installation.
Usually when I get a script it's a zip file but this is a rar.
How do I get it open?

by winrar u can open .rar files , u download winrar from the internet i dont remember the url but i once downloaded it to open a .rar file.

hope this helps you

Thanks, I found the site, but look at the downloads page:

http://www.rarlab.com/download.htm

What do I download? What is all that Graphic and command line stuff???

try Tucows

Tucows was down for me, try download.com

Pick one, there's a bunch right here.

OR

Here is a free one.

I haven't tried any of these so I'm not sure how they work.

try open it with winrar or winace, you can download them totally free from http://www.softonic.com , this web is a spanish web full of shareware, freeware... very good!!. If you don't understand spanish, try using the search butto in the left of the page.

I have the script open and already installed.
Thanks, all.
