However, maybe you need to give us additional information because the only
time that you would need to do this is if you uninstalled Office and then
re-install it. Part of the installation process includes the option to
Activate the product. Did you re-install?
Another time you may need to reactivate, which frustrated and inconvenienced
me recently when I hired some PCs from a rental company, is when you make
certain hardware changes to your PC since installing Office.
