Reinstall Office from your CDs.
To save time and keep you from having to post back here and say you don't
have the CDs:
1. If this is a "borrowed" version of Office and you don't have the
installation CDs, then you are just SOL. You'll have to go to a store and
buy it.
2. If Office came installed on your computer, you *do* have the CDs. They're
in all that mass of stuff that came with the computer that you put aside to
look at later because the computer was working fine without your having to
figure out what all you had there. Look carefully through all that stuff;
the CDs won't necessarily be in a jewel box--they may be in a cardboard
folder or even just an envelope--but there will be a Certificate of
Authenticity that provides the CD key code. If you find that in fact you
*don't* have the CDs, then contact the OEM and demand them; OEMs are
*required* to provide CDs for any Microsoft software they install on a
computer.
