unattended installation of Windows MultiLanguage Version is not working

Sad
I want to install multiple languages using unattended installation as described in the site :-http://support.microsoft.com/default.aspx?scid=kb;en-us;289125

I used below command to install the languages.

rundll32.exe shell32,Control_RunDLL intl.cpl,,/f:"c:\regopts.txt"
But it does not work in Windows Vista. Is there any other alternative approches to install multiple language as described in above link. Pls let me know.
Thanks and Regards,
