Office Mac Q

how can i change the serial number info in Office (mac)?

I think you can just delete this file:

/Applications/Microsoft Office 2004/Office/OfficePID

It’s a hidden file. You’ll need to have Finder set to show all files (only available with other tools like TinkerTool I believe); Terminal works too.

Maybe some Office preference files too in your ~/Library/Preferences folder.

The Office Removal tool works also. That’ll remove all of office (preferences too?). Then re-install.
