How did you aquire Pages, if you never got the media then navigate to the Mac App Store, click purchased and then redownload and re-install. If you still can't then you probably need to call AppleCare telephone support. It's free if you either bought AppleCare or the machine is less than 90 days old.

What are you opening?
If it is a .pages file and not Pages itself, then you do not have it installed.
Go to the Mac App Store on your Dock or in Mission Control.
and type Pages in the search field and install it. It does not come with your Mac when you purchased it, unless you checked the iWork option with your Mac on the online store.
