Ok, I've had enough of this 64 bit crap. Nothing I want to use works on it. I'm sick of it, I need 32 bit for everything I use. Must I buy another home premium for 32 bit?
No, you do not need to purchase another copy of Vista. You can use your same product key number from your 64 bit Vista Home Premium to install the 32 bit version of Home Premium from a Vista 32 bit installation DVD that is the same type (retail or OEM) as your 64 bit DVD.
