Office 2003 source doesn't match installation source.
Uninstall from the setup binary on the CD.
Go to Control Panel -> Add/Remove programs -> Remove Office 2003. For some reason, it isn't removed from this list. this causes many headaches later and took me a few hours to figure out.
Reinstall from CD.
