If you need to open a PDF or XPS file in Office 2007 you can with a free addon.
Shortly after upgrading to Microsoft Office 2007, I ran across this nice free add-on from Microsoft, which allows you to save your documents in the Adobe PDF or Microsoft XPS format using all eight Microsoft Office 2007 applications. I use the feature almost daily, so I’m sure all you guys will appreciate the find.
Update: Modern versions of Office no longer need this extension. Saving files as a PDF or XPS is a function that’s built-in.
