Operating System Language Check and Office Installation

Hi,

I am deploying Windows 8 images in multiple languages.
Now I want to install Office 2013 from network share depending upon the OS language.
For example a kind of First Run command that query the OS language and if install the correct office language from share.

Office Share: I have mounted OPK office's here ... director structure look like:
                      N:\Office2013\Eng  , N:\Office2013\Swe

And under each folder, there is bat file OEMSetup.bat.

Any thoughts how to automate.                  

N.A.Malik
