Error. File not found. C:\windows\system32<LANG_NAME>\mstsc.exe.MUI

A workaround is to set the Windows version to XP but I don't like it because
Wine as far as I know doesn't allow to set a per application Windows version
and my default Windows version is set to 7.

strace shows that Wine doesn't even attempt to find MUI files as if some
resolution inside it breaks completely when Windows != XP.
