well, i havent had a problem yet installing "apps" during cmdlines.txt - in fact it is the only way I can since noone can figure out whats wrong with my svcpack.inf. The only ones I install that you seem to think I have a problem with are MDAC, DX9, MSJVM, IE6, MM20, WMP, WJV...I believe that is all...but they always install (well, minus WJV cuz I run that during runonceex). I dont see why it would be any problem at what you install during either t-13 or t-12...I was told they are virtually the same just one runs first because one always has to run first in anything you do, or they would run at the same time and might cause an error (see the logic behind it?)
