So, I'm assuming that u meant that the nLite's RunOnce n the RunOnceEx is basically the same, is it? Actually, I need this feature to make a downsized, slim, clean installation CD for my laptop. However, some of the drivers are in .exe file and cannot be extracted coz it comes with some programs to make the device works (e.g. volume control indicator, etc...). Basically, I juz wanna run these driver installers on the first logon... Can u give me some example for the usage of RunOnce in nLite?
