      MSVC 2015 compiler (tried both 32 and 64 bits).

      In a dialog opened with QFileDialog::getOpenFileName(), opening a file by double-clicking on it leads to the following warning:

      shell\comdlg32\fileopensave.cpp(14247)\comdlg32.dll!00007FFF47C9EAD8: (caller: 00007FFF47CD0258) ReturnHr(1) tid(1438) 80004005 Unspecified error
    CallContext:[\PickerModalLoop]

      If I just click on a file and press Open, there is no warning.

      I have attached a full sample project, but I guess just this line in any project will do:

          QFileDialog::getOpenFileName(this, tr("Open File"), QString("C:\\"), tr("All Files (*.*)"));
