My only guess is that it's having a problem because I'm choosing the Trial License instead of actually providing one.
Yep, that was the problem. Can not use Silent Install or Unattended install using install.xml file if you are selecting the Trial Version. Must have a valid Volume License.
Another thing, the Adobe Log File created is not in a plain text format. It is compressed so you will need a Zip program to un-compress it before you can read their Log File. ... nice(sarcasm added).
