I want the xp codec pack to be a part of my unattended cd and i want to use a bat file at the end of the setup i already tried to use the switch /S and it removes everything except the choose language dialog anyone know what i can do to avoid that!?

Try /S (uppercase), that´s how older versions installed silently.
Regards

Thats what i already use so it aint working

But you right the lowercase /s don't work at all

capital letter not small
/S

i use /S but it aint skipping the language selection box

*EDIT* I solved the problem with autoit =]

CODE:
run ("XP_Codec_Pack_2.3.6.exe /S")
WinWaitActive("Installer Language")
Send("{ENTER}")
