Distiller API reference to the PDF printer

Hello, 

  I was using the Acrobat Distiller API reference to the Adobe PDF printer. The API reference allowed me to eliminate the popup for the pdf name by defining a key that contained the name of the PDF file. This interface worked fine on a Windows XP Pro machine.

  So I changed over to Windows 7 (64 bit)  and Adobe acrobat (Version 10.1.5) and the distiller API reference not longer

works, I cannot get a PDF file to be created. So does anyone have any idea why the distiller API reference is not longer working on a WIndows 7 (64 bit) machine?
