I just got my 64 bit upgrade in the mail. Its the 20 dollar up grade version not the ultra version thats next step up fromt he premium vista. Im gonna do a copmlete format and install of vista on my system and was wondering how i would install the 64 bit software? Do i freshly install 32 bit then as soon as windows loads up I should install vista 64 bit? Or should i install all my drivers for my devcise's then install 64 bit? If this is a stupid question then im sorry i just wanna know.
