All Vista DVDs are basically the same, since the install process is now
a Imaging type setup. A Dell branded DVD would only have the OEM
content added. It's likely your setup still has an incompatible program or
driver that is causing Vista upgrade to fail.

Most people would advise you to do a Fresh/Clean install of Vista. This
isn't always practical for OEM owners as they loose the 3rd-Party apps
the OEM provides. Doing an upgrade requires a fair amount of prep
work. The Upgrade Advisor doesn't always indict everything that can
cause an upgrade to fail. Has the Dell been "De-Dell-ified" ?, have all
the non-essential or unwanted programs removed from it. Doing a
Vista upgrade requires that the machine is properly prepared before it
will take the upgrade. Have you checked for a BIOS upgrade for the
dimension and that all primary devices have Vista drivers available ?
