You're looking in the wrong place. The PDF/XPS feature is not considered to be
an add-in.
Click the Office button and hover the mouse over the Save As item; the "PDF or
XPS" command is on the menu that appears to the right. Alternatively, click the
Save As item and change the "Save as type" dropdown in the dialog to PDF or to
XPS.
