When I add command below in "RunOnce" in nLite, Office installs ok at the end of Windows installation (when Windows starts first time, bat command is executed and Office installs). But I would like to be able to install it like the other nLite addons, when Windows installation countdown is still active (before installed Windows starts for the first time). Is that possible somehow? start /wait %SOURCE%\Addons\Office2007\setup.exe /adminfile Office2007.MSP
