To start the app installs, my winnt.sif calls start.cmd under [GuiRunOnce]. For Norton Systemworks 2003 the line in start.cmd is start /wait %systemdrive%\install\norton\setup.exe /qn /Reboot=Suppress This is the switch i found on one of the stickies, but for some reason its not working for me. What happens is that a windows installer box pops up displaying a list of switches (it lists the reboot switch as /norestart). When you click ok to the dialog box, it skips the nortons installation. I have also tried the /norestart switch but niether seem to work. Any suggestions?
