Can any version of Office 2007 be installed from any DVD?

In other words, is it the same as Vista in that you can install any version with any disc; it's just the product key that defines what version will work?

Reason I ask, is because my parents have an Office 2007 license, but no disc. I've got a disc, but their license is for Ultimate, and my disc is for Home & Student. Can I use my disc just to install it when I'm up there at Xmas, but use their key during the install process?

Thanks muchly.

I think so, if not I think you can download Office from the Microsoft website, I think if you get the demo for ultimate the key unlocks it.
