Software Deployment

After reviewing the inforamtion in the KB's and unable to find anything specific to this, I figured I would post the question.
We are trying to automate the CS4 install, which works completely with exception to one prompt.
It appears that during the Adobe AIR install, it's attempting to go to the internet to download something. Since our users are "users", the SMS account is used to deploy the software. This forces a proxy authentication dialog, which can be canceled and will continue on error free. This posses a problem for us installing this during the night, or when people are away from their desk.

We found an entry in the AdobeAMP-mul.proxy.xml which is being used to direct the AIR installer, that gives reference to the .air file. My suspicion is that this file is what is attempting to be upgraded. Just curious if anyone has seen something similar or if anyone might have any other thoughts about how to stop this from happening.

We've pretty much ruled out allowing the SMS account web access, and having the users click cancel is not a good option either. Just hoping for something a bit more elegant.

Thanks in advance.
