Do you have any previous versions of Office installed, or was Office 2007
Trial or something else previously installed? I'm just wondering if there's
something hanging on from a previous installation.

My initial thought was a problem in your Vista installation or
configuration, since you can install the DVD on another system...Any chance
you could try to repair your Windows installation?

Do you have administrative rights on the system? Have you tried installing
as administrator?
