...under Q. How to add additional applications... is a screenshot of the Add an Application dialog.

Can anyone show me a list of the Command line arguments & definitions that can be used? Not just the /q/n/z shown.

I can't access that page to see what it says. For specific program application switches, I find the best source of info to be msfn.org who are dedicated to "unattended/network/silent" installs. Hope that helps

I did try the MSFN.org site 6/1/07 but have not gotten an answer, and a search does not help.

The posts I can find deal with issues around unattended installs, but all do not explain the command line options for adding applications.

Still need a list. Preferably a full list, or at least an explanation of the /q/n/z options in the screenshot.

Give the Microsoft Technet Forums a try I think tecknomage. Perhaps the Windows Vista IT Pro>Windows Vista Deployment and Imaging sub-forum is the appropriate one to pose your questions.
