Do I get 64 bit if i get 32 bit

I was wondering that if I get the premium version and I click on lets say the 32 bit do i get the 64 bit as well or
do i pay seperate for both.

I would really rather have both just to try them out

Iam not a computer whizz but I heard that 64 bit is faster so I just wanna check myself.
I also heard there is like compatibility issues with the 64 bit

Hi,

as they are seperate products you would have to purchase both, download the free versions first to check them out then decide which one you want!!.
