Installing Office 2007 from a custom dvd

[Zacreth]

So I've programmed OCT to chain the install of Office, Project, and Visio with the keys and all to the point where all I have to do is insert the dvd into the computer and I don't have to do anything else. In Windows XP that is.

The problem now I face is that testing the same dvd in Vista will only allow me to install Office and the chain never finishes installing the other software. Is there something in Vista setup so that I can't do this or is it an argument maybe that I am using in OCT?

Any info would be greatly appreciated.
