title: Run button is disabled in Qt Creator
body: <p>This happens even on a <strong>freshly created, empty project.</strong></p>
  
  <p>The Run (and also Debug) buttons are disabled for the Qt5 configuration (they're enabled for the Qt4 configuration). The build button is not disabled, however, and it works - I can build the project, but I can't run it from Qt Creator.</p>
  
  <p>They are disabled in the Build menu as well. Everything is enabled and works fine for the Qt4 configuration, however.</p>
  
  <p>It's a Qt/C++ project, on Windows 7 (32-bit).</p>

  <p><strong>Edit:</strong></p>
  
  <p>I found a couple of related questions - <a href="https://stackoverflow.com/questions/6631241/run-button-no-enable-in-qtcreator-for-qml-project">RUN button no enable in QtCreator for QML project</a> and <a href="http://qt-project.org/forums/viewthread/15737" rel="nofollow noreferrer">http://qt-project.org/forums/viewthread/15737</a>, but they have slightly different circumstances, and they don't show a clear solution. I'm posting them in case they help, though.</p>
  
  <p><strong>Edit 2:</strong></p>
  
  <p>I checked the run configuration for Qt5, as suggested by @Blueman and @Fabian, and the executable field is empty (and also disabled), even though the Build configuration correctly specifies the path. Moreover, I get this error - "The .pro file untitled2.pro could not be parsed." Here's a screenshot:</p>
