Hobbywing LCD Program Box USB download

[HOTSHOT III]

I purchased an XERUN 150A R/C Car ESC and an LCD Program Box:

Reading the instruction manual for the program box it tells me to download the USB LInk Software, but when I try and do this my computer says "windows cannot open this file".

Currently I have downloaded the software, but there seems to be no way to run the aprropriate file as the instructions say. To help anyone reading this my computer has Windows 7, and Internet Explorer 9 and Mozilla Firefox browsers. I've tried using both browsers but in both cases there seems to be no way to run the file. Hope someone can help!
