32 or 64 download link? In the app I see these and maybe a third option that I don't remember. 

I forgot what they told me which is better, it'S not always the higher number with these things I think.

If your computer supports it (and it probably does) you want the 64bit version. If you can't run that one, try the 32bit one (which is sometimes called 86x, which might be were your confusion comes from).
