I haven't tried every app, but so far ID, PS, and Illustrator only show my previous Acrobat 9 as an option to print a PDF file. When I use this option, nothing happens. If a file is created I have no idea where it is, since I never get to the point of being able to name it or give it a destination. Can anyone help me get Acrobat X working?
On a Macbook Pro...
Sounds like Acrobat X might not have been installed, but I'm not sure that's relevant. What version of Mac OS? Since Snow Leopard print to PDF no longer works the way it used to. See InDesignSecrets » Blog Archive » Acrobat’s Adobe PDF Printer Replaced in Snow Leopard
For Exporting PDF, the recommended methos to creat PDF from ID, or to save PDF directly from Photoshop or Illustrator, Acrobat is not involved at all. You should tell us exactly waht you are doiing, and waht error messages, if any, you see, as well as waht you expect to happen, and waht happens instead.
