EDIT: So this me right now......you convert said .au3 to an .exe, thats bout far as ive got so help me out here im guessing now you then put the .exe and the installer for wuteva program into a folder on the installation disc dunno which folder like wether you create one or they need to be in a certain folder then you add commands to the winnt.sif file to run the .exe you created with autoit.....Is this about right plz ?
