log generated while runing the game launcher

The launcher will not open if wine mode is Windows Vista and later like Win 7
and Win 10.

The launcher work fine in Windows XP mode, the main game run too, but the CEF3
component used for authentication will not.

In Windows vista mode and later, the launcher not work.

The main problem is between the game launcher only and dwm (dwmapi) at Windows
Vista mode and later.
