Nice guide. I'm sure i would give it a try to replace my chained instal i have now. But i still have some questions: is it also possible to integrate mui Packs in the installation sources? Or must i keep these installed with chained install? And how should I slipstream updates for the MUI packs? On the moment i have problems with the installation log. If i use the runonceEx command HKLM,"%RunOnceEx%\install20",1,,"%11%\msiexec.exe /i %CDROM%\Apps\InstallOffice2003\pro11.msi TRANSFORMS="""%CDROM%\Apps\InstallOffice2003\Custom_Setup_1.MST""" /qr /lpiwae """%logdir%\Office Setup(*).log""" "
