There are many versions of Office and of Office 2000 and some are made on more that one disk, Publisher being on the second disk, PhotoEditor, Powerpoint and Frontpage on others, there is one version where the basic version of Publisher is part of a one disk install. During the installation you might have noticed an item on do you want to install common components or do you want to select others, then you could have ticked box's to add others, at that point you should have been able to select whatever you decided to include.
Common components may not be the exact wording but it is similar.
if you have a larger hard drive tick
"all to be run from the hard drive"
