Hi, I am having a problem that I am sure is something I am doing wrong.  I have used previous versions of nLite to successfully slipstream my OS but did all of the adjustments in one nLite session.  This time I am using v 1.3 and use four sessions:  Session 1 - integrate SP2 + several hot fixes, Session 2 - integrate many hot fixes, Session 3 - integrate WMP 11 via WMP 11 Slipstream and Session 4 - integrate IE7 + 2 IE7 Hotfixes + component removal and tweaks.  It seems like on the last run the Autorun.inf and Setup.exe files dissappear from my source directory. Previously when I used nLite to integrate SP2 and all of my hotfixes in the same session I had no problem.  This time I decided to split the job over multiple sessions being carefully not to remove any components until my final run.  I monitored the source file on all runs except the final one and saw the autorun.inf and setup.exe files.  I assumed everything was OK and failed to check after the last run, prior to executing a direct burn of the slipstreamed OS. Does anyone know what I am doing wrong?  And, am I correct in assuming that I can change my approach and use one session to do this work, going back to integrate components until the last pass? I attached the log of the last session.  Since the OS I am integrating is an upgrade, I decided to use an attended installation. Thanks, ErgoMan Last_Session.ini
