It would be my guess that you are using an app like Word, from the Office,
or Works Suites. These have Product Keys of their own, and are usually on
the container for the reinstall disk. (Sometimes this is an 'applications'
disk in the set of system disks.)
If you cannot find the Key, you are going to have to save all your data, and
restore the system to 'factory defaults' to get that Key installed from the
original setup (assuming the app was part of the preinstalled system). My
way to do that would be to use the Windows Live 'Sky Drive' storage.
