Hi,
All new GOG installers ("v2") require functions from the gdiplus DLL (
http://www.playonlinux.com/en/commentaires-1111.html ).
You can either use a Wine version >= 1.5.9, that implements enough of the gdiplus API so that the installer doesn't crash; but some of the installer interface is black, because part of the implementation is just a declaration ("stubs").
Or you can install Windows' gdiplus.dll with the gdiplus "component", either by selection "install components" option then "POL_Install_gdiplus" during manual installations, or using the "components" tab in the Configure window (Configure button > select virtual drive > Install components tab > gdiplus).
GOG install scripts call the POL_GoG_install function, that among things install the gdiplus component and work around the problem silently.
