Dorel,

I don't think you can automate the installation of a Language Pack via
the WUA without invoking Lpksetup.exe :

Understanding Language Packs
http://technet.microsoft.com/en-us/library/cc766472(WS.10).aspx

" You can install a language pack to Windows in one of the following ways:

* Install language packs directly to a mounted Windows image by
using Package Manager. This scenario is useful if you create a single
image that you can deploy across your organization. This is the typical
OEM scenario. For more information, see Install a Language Pack to an
Offline Image.
(http://technet.microsoft.com/en-us/library/cc749047(WS.10).aspx)
* Copy language packs to the \Langpacks directory of a Windows
distribution. During Windows Setup, the language packs will be installed
to the computer. This scenario is useful if you do not intend to edit
the Windows image and intend to provide support for multiple language
packs where necessary. This is the typical corporate scenario. For more
information, see Copy a Language Pack to the Windows Distribution.
(http://technet.microsoft.com/en-us/library/cc765987(WS.10).aspx)
* Use the Language Pack Setup tool to install a language pack. The
Lpksetup.exe tool must run on a running Windows operating system. This
scenario is useful if you change the installed language of a running
Windows operating system. This is the typical end-user scenario. You
should only use this scenario for language packs that are stored outside
of the Windows image. For more information, see Use the Language Pack
Setup Tool to Install a Language Pack.

The automated installation of LPs is way beyond my skills so if I'm
wrong, it won't be the first time. <w>
I'm not even certain which newsgroup to refer you to.
