How to programmatically disable prompts for output file names in Acrobat X

Question

My code to programmatically disable output file names (below) is not working on a Windows 7 64-bit machine using Acrobat Distiller X.  It works perfectly on a Windows XP machine with Acrobat Distiller 8.
The latest API Reference I was able to find is dated June 2008.  My logic follows this convention.
I have confirmed that the registry key is updated as specified below.  I have also confirmed that I am able to write to the directory indicated.
Please provide any suggestions to resolve. 
Thank You!

I remember seeing that the problem is thunking. A little more specifically, because it's a 32-bit driver but a 64-bit executable, there's a 32-bit system spooler process which will always show up as the EXE name.
