Sure, and Microsoft supplies the tool for doing it. Just launch Offices Remove Office utility (found at /Applications/Microsoft Office 2004/Additional Tools/Remove Office). With Remove Office open youll see the Welcome to Remove Office window that bears a Continue button at the bottom-right corner of the window. Hold down the Option key and yow, aint that somethin! the button name changes to Remove Licensing Information Only. Click that button, acknowledge that this is what you really want to do, and Remove Office will go about the job of deleting the files necessary to launch the Office Setup Assistant (where youll be prompted to enter your name and product key) when you next launch an Office application.
