Have a look the Document menu, Extract Pages... option.
In my Documents menu,there is no option of Extract Pages.The options that appear are as below
5)Accessibility Quick Check
6)Use local fonts
Where else can I find the Extract pages option ?
Are you sure you have Acrobat? Look under Help - About. What does it say
Also, the name of the menu is Document, not Documents.
Adobe Reader can't extract pages.
Bernd nailed it. You don't have Acrobat, you only have the free Reader.
