What happens when it downloads? Does it get blocked? Do you get an error? I think there isn't x86 (32-bit support) yet so you won't be able to run it on 32-bit systems. What is your processor so I can be sure?
Did you properly extra it or are you trying to open it through the zip file? You need to right-click then extract it. If you did that, then make sure your antivirus isn't blocking it. When you try to run it, what does it do? Anything?
