Office 2003 Updater fails

The admin before me made some ‘Quirky’ settings on some of the older systems here and I’ve run into some issues. The big one is I cannot get any Office software to update. It downloads then fails to update. I’ve checked permissions on the C drive (only hard drive) and checked areas in the registry where you can deny Office updates. Nothing. This person was ‘unconventional’ in their approach. We are at a public library so our public machines are locked down. But nothing this person did before me makes any sense and I can’t find any documentation (or logic for that matter)

Anyone have any ideas what could cause Office to not update? Windows updates fine. Just Office is the issue.
