What you pretty much do, is you find a Wine download for your linux OS and install it. Once wine is installed you set some preferences up and then you can download the exe from our site here, open the exe with Wine, and then install it onto an imaginary windows proportion wine made earlier.

I'm no expert though since I've only used it once or twice before.

DO NOT download WINE package from the Internet and install it manually because then it won't be automatically updated! You can find the instructions how to install it properly to your Linux distro here: http://www.winehq.org/download/
