Since this doesn’t seem to be posted anywhere and wherever it is posted, it seems incorrect or overkill to reinstall Office 2008 entirely. In my case, there was a typo that was just an annoyance that needed to be corrected. I could see though if the Office Suite was installed for a previous user / employee and was not set to a generic name, it could be annoying as well.
Many sites tell you to go and remove the
/Users//Library/Preferences/Microsoft/Microsoft Office 2008 Settings.plist
Which is great, unless you do not have it.
There are many hacks out there to help with Windows and Office on Windows registration information correction, but nothing out there for OS X and Office 2008 which is a hassle. I didn’t want to reinstall everything just to fix my typo, so after some investigation I found
/Applications/Microsoft Office 2008/Office/OfficePID.plist
1. Copy/backup the OfficePID.plist file (in case you mess it up).
2. Quit out of all MS Office 2008 applications.
3. Open OfficePID.plist in Property List Editor (comes with XCode Development Tools)
4. Under the Property List Root/1000 is the entry for the user name. Fix it.
After that, open up Word and other Office 2008 applications and see the corrected name.
