Software Deployment

Hi guys,

i'm trying to deploy a languagepack for Visio 2010 Professional.

I had already deployed a project that install Visio 2010 Prof in an english user interface.
The installation works successfully.

My problem is, how to deploy a Visio 2010 language user interface for Visio pro 2010 in german?

I already configured a config file, called config_DE.xml.

My Folderstructure looks like this:
%SYSTEMDRIVE%\Office\Visio2010Pro\ (<- inlcuded installationfiles of Visio 2010 Prof. and setup.exe)
%SYSTEMDRIVE%\Office\Visio2010Pro\language-configs (<- included config_DE.xml)
%SYSTEMDRIVE%\Office\Visio2010Pro\Visio.de-de (<- language files)

In my Config_DE.XML -File I include this following parameters:
<Configuration Product="Visio">

<Display Level="none" CompletionNotice="no" SuppressModal="yes" AcceptEula="yes" />
<AddLanguage Id="de-de" />
</Configuration>

I start the language pack installation with this commands in cmd shell:
%SYSTEMDRIVE%\Office\Visio2010\setup.exe /config %SYSTEMDRIVE%\Office\Visio2010\lanuage-config\Config_DE.xml

But the Workstation (a fresh system) works about 2 minutes and then the proccess setup.exe terminated.
If i start now Visio, the language is not installed (i looked in file->options->language).

Can anyone help me, please?
