Trying to install Office 2007 on our Vista desktops as Dynamic Admin. Regular users are power users so we need the elevated user rights. We can install the app manually using the same procedures as the bundle, but the bundle throws a "1603" MSI error. We don't get this error when running the command manually, nor do we get it when run as a regular user who is an admin. What's the dealeo?!

setup /adminfile "officecustom.msp"
In the OCT, we set to run with no interface, no modal, and no completion info. (completely silent as MS suggests.
