Help meeeeee please

Hy all

First, sorry for my bad english.

Second, : I need help.

I create my first unattended XP SP2 DVD, but i have some errors i think, because when launch

my "start.cmd", in first logon, 2 or 3 program start install in same time.I use nLite 1.0 RC6, integrate

hotfix, some add-on and tweaks.

My questions is , how can I stop the second .exe to start, or paused "????" time, while the first app is

installed completly?
