PokerAceHUD wtf

when I open it, I am told I have to update to newest version and am given a link :

http://www.pokeracesoftware.com/hud/download.php

when I downlaod the laterst version it isn't openable as its downloaded as "all files" and not an .exe or something that most setup files usually are.

Does anyone using PAHUD get that same update and unable to download from the page know how to do it?

thank you
