I have been successful in creating the fully automated unattended windows xp (professional). Now i want that my favourite applications like Microsoft Office 2003, Windows Media Player 10 etc should also get installed. I have read the pdf (MSFNUnattended) file and it has explained different methods like GUIRunOnce, WPI, XPLODE etc but haven't explained them thoroughly or i am so much confused. I have tried GuiRunOnce method but my applications are not going to be installed, when the setup completes. And the error it gaves me is this Cannot find c:\install\Applications\fdm\fdminst.exe, for all the applications that are listed in the start.cmd file. I have used %systemdrive% variable in start.cmd Plz Help me to follow which one is the simplest among GUIRunOnce, WPI, etc for installing the applications. I would be very pleased if you help me in the following way: Step 1: Do this Step 2: Do this Step 3: ...... Hope to hear!
