link works great if your running a silent install from a hard drive. problem is getting it to install silently from a DVD (which could be any drive letter) I can use variables to find the exe and the install.xml however, the xml file has exact file locations and so far no variables have worked for me in the xml file. I tried using AutoIT to (right before the CS3 install) rewrite the xml file with the correct drive letters, to the local drive. but it doesn't seem to work... for some background, This is for a unattended OS DVD which would install the Master collection silently.
