Hi, As a workaround you might try to install windows runtime libraries using "winetricks vcrun6", "winetricks vcrun2005" or "winetricks vcrun2008", depending on which compiler/library the developer of your app used. You could still file a bug, because if this call works under windows, the builtin function in wine should be able to cope with it, too. Maybe wine expects a different format, in some samples I goggled, a more verbose format like "German_Germany.1252" is used instead of just "german".
