Installation of Language Interface Pack

Question

My laptop has Windows Vista Ultimate x64 as its operating system. I wanted to install Hindi Language Interface Pack and so downloaded the LIP from microsoft downloads.
As per the given instructions, i clicked on the pack to install it. The Microsoft Language Installer runs and asks me to point the folder where the language pack is available. I browse and point to the folder of the mlc pack but it says no language packs found.
Please guide me in this regard.
