I have 32 bit Vista on my home built computer but I think it can handle a 64 bit Windows 7.
Yet when I tried to install 64 bit Windows 7 it would not allow me to (at first, anyway, unless there is a trick). The installation program checks what OS you currently have rather than the hardware.
How can I do a 64 bit installation of Windows 7?
