Adding to the previous excellent answers
This is not a bug in Vista but rather it is a common problem when installing a Trial of Office 2007 OVER a previous version of Office that was not a Trial instead of installing it to a different directory.
You need to uninstall all reference to all Office installs including the previous version(s) and then re-install Office 2003.
For further help on this issue I suggest that you repost this to one of the Office newsgroups as per below
