Every time I try to click on the link to download it on the page (this is the link I am trying to donwload it from.)
But when I try to download it from the list of all the older versions I get a huge list of options and I dont know which to download it form.(link that has the list of all older versions.)
I found out that the link to download it was not working because I was on chrome but even if I go on some other browser and try to install it, it would download the 32 bit version. So I downloaded it from here.
Also this video helped.
