Does Adobe PDF Creation Add-On 9 need to be purchased or is it a free download?
This is a free add-on but it comes with Adobe FrameMaker 8. You are presented with the option during the main installation. Adobe Acrobat and Adobe PDF Creation Add-On can't coexist on the same system due to compatibility issue. It seems that the add-on can't be obtained through downloading. Visit the official website of Freemaker for additional information.
