[X2Go-User] x2goclient: english version not installable

I'm trying to install the English version of x2goclient on Windows 7. During the installation process I can select German or English, but regardless what I select there, the installer always installs the German version.

I've downloaded x2goclient 4.0.2.1 version from http://code.x2go.org/releases/binary-win32/x2goclient/releases/ I've also tried older versions from this directory, but still got the same result, the english version is selectable but isn't installed after selction.

I have this problem on both german and english version of Windows 7, 64bit.
