Windows 7: How can I do a 64 bit installation of Windows 7?

How can I do a 64 bit installation of Windows 7?

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.

You need to boot from the installer. 64 bit can not be installed from a 32 bit OS, and vice versa.

If you have an Upgrade version, the DVD will scan the HD to see the other OS and allow use of an Upgrade key.
