If it really is missing eg because you have formatted the disc, then you
will need to re-install from the CD. I suspect it is just the link that is
missing. Search for winword.exe and create a shortcut to it (or re-run setup
from Windows Control panel add or remove programs and check the option to
restore shortcuts.)
