wine users - Oct 2010 - Office 2010 German "error install language unsupported"

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

What could I do?

You can try starting it with

Code:
LANG=de_DE.utf8 wine setup.exe


but even if it works it will probably just get you to
http://bugs.winehq.org/show_bug.cgi?id=24605

So far no one has reported success in installing Office 2010.
