Nero 7 Lite is now also localized into Chinese Simplified My unattended parameters are these: "%CDROM%\Software\nero7\nero.exe /VERYSILENT /LANG="Spanish" /TASKS="desktopicon,imagefile_assoc" /COMPONENTS="nero_toolkit\nero_cdspeed,nero_toolkit\nero_drivespeed,nero_toolkit\nero_infotool,nero_core,nero_core\nero_express,nero_core\nero_api,nero_core\nero_audioplugins,nero_core\nero_audioplugins\mausau,nero_core\nero_videocd,nero_core\nero_sounds,nero_coverdes,nero_waveedit " /USER=*** /COMPANY=*** /SERIAL=****-****-****-****-****-****-****"
