user: bro I have 32 bit windows 7. The game needs 64 bit to play. How can i get it ?
user: will it work if I install my windows twice?
IT guy: Yes install it twice you will also get windows 14.
user: thanks a lot man. You are a legend

So that's why some windows has x86 folders, they must have installed 32 bit windows 2.6875 times.

@perfectdark in my experience all 64bit Windows have an x86 folder where 32bit programs are installed by default, while the non-x86 folder keeps the 64bit programs.

A bit annoying in my opinion, but in the rare case you want both versions of the same program... (I'd install both in the same folder with identifying names, but whatever)

Typical windows user...
