[Wine] Office 2010 German "error install language unsupported"

[scenox]

Hi, I'm trying to install Office 2010 German version, and I get the following error some seconds after the office splash screen:

error_install_language_unsupported

I have Arch Linux, German setup, also winecfg appears in German when I start it. Wine version 1.3.4-1

wine output until the error message appears:

Code:
wine setup.exe

wine output after the error message:

What could I do?
