Hi All, I've been at this for a couple of weeks now and I'm getting frustrated... I've setup RunOnceEx according to the Definitive How To Guide from here; http://unattended.msfn.org/unattended.xp/view/web/31/ here's what my cmdlines.txt looks like; [Commands] "rundll32 advpack.dll,LaunchINFSection nLite.inf,nLiteReg" "RunOnceEx.cmd" here's what my RunOnceEx cmd file looks like; cmdow @ /HID @echo off SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx REG ADD %KEY% /V TITLE /D "Installing Applications" /f REG ADD %KEY%\020 /VE /D "Novell 4.9" /f REG ADD %KEY%\020 /V 1 /D "%systemdrive%\install\Novell49\setupnc.exe /qn" /f REG ADD %KEY%\030 /VE /D "McAfee Antivirus version 8.0" /f REG ADD %KEY%\030 /V 1 /D "%systemdrive%\install\mcafee\setup.exe /qn" /f REG ADD %KEY%\035 /VE /D "Java 5.0.6 Runtime Environment" /f REG ADD %KEY%\035 /V 1 /D "%systemdrive%\install\java\jre506.exe /qn" /f REG ADD %KEY%\040 /VE /D "Adding user,Cleaning Up and Rebooting" /f REG ADD %KEY%\040 /V 1 /D "%systemdrive%\install\cleanup.cmd" /f EXIT I create my ISO using nLite, I boot the computer, windows installs beautifully BUT, not the RunOnceEx file. It DOES work however, when I execute it from the command prompt; START>RUN> rundll32.exe iernonce.dll,RunOnceExProcess On that same note, I can't seem to find winnt.sif to remove [GuiRunOnce] so that it doesn't interfere with "my" setup. So I am at a loss as to what to do next and I would really apreciate some help. Thanx
