Whoops, this was Qt 5.4.1 .-. Here is the link for Qt 5.4.0: https://download.qt.io/official_rel...nsource-windows-x86-mingw491_opengl-5.4.0.exe (but if you want to use Qt 5.4, I recommend to use Qt 5.4.2, because it doesn't add new features, but fixes some bugs: https://download.qt.io/official_rel...nsource-windows-x86-mingw491_opengl-5.4.2.exe
