Thrawns revenge steam install

[Steals]

So I know it says to follow the manual but it came out as goobly goop from the site I downloaded it at...I'm not super computer savvy but it came out in a bunch of text like


KdÒùfOÝn* and so on

If someone could either provide a link or copy/paste the guide here I'd be incredibly thankful!

Just for clarification I downloaded this file http://www.moddb.com/mods/thrawns-revenge/downloads/imperial-civil-war-21-zip1

its currently in my downloads folder  ...if anyone could guide me as I'm a total DERP with this stuff I'd be eternally thankful <3
