Change Office Xp Key?

[stinkypete2000]

Is there a way to change office xp key like the win xp key changer program? I slipstreamed office xp sp2 and did a admin refresh to update my office install using a key from the keygen program and after install, office says invalid key and wants me to activate it. I did try to gen a office corp key but guess it did not work. short of uninstall and reinstall, is there anything I can change?

thanks
