Additional information

Adobe Acrobat 8 Professional is installed with the Design Premium, Design Standard, and Web Premium versions of Creative Suite 3. Although Adobe has tested Adobe Acrobat 8 (Standard and Professional) on Microsoft Windows 64-bit operating systems running on a 64-bit processor machine, there are known limitations.

As the Adobe PDF printer is not supported on 64-bit operating systems, the 64-bit version of the AdobePDF.dll does not get extracted during installation. Therefore, the installer can't locate it. While Acrobat is installed, the Adobe PDF printer isn't installed. Following the update procedure above addresses the issue.
