      I just uinstalled Qt 5.5.1 and installed Qt 5.6 (but above is the new project created in Qt 5.6). I added
      QT += multimedia
      in my pro file. I use MSVC 2013 (as alway when using Qt), Windows 7. It builds program and when I click Run, it works, although it shows in Application Output: 3x failed to access to the graph builder. I could ignore it, but I am not able to access to Design mode ("Cannot open this QML document beacuse of an error in the QML file"). Could you help me to solve it?
