title: Qt5Widgets.dll is missing?
body: <p>I'm using Qt5 with the Qt Creator.</p>
  
  <p>My program works just fine if I launch it from the Qt Creator itself, but if I try to run the <code>.exe</code> file from <code>debug</code> or <code>release</code> folder, I will only get an error:</p>
  
  <pre><code>The program can't start because Qt5Widgets.dll is missing from your computer.
  Try reinstalling the program to fix this problem.
  </code></pre>
  
  <p>I'm new to Qt and have no idea what's causing this, didn't find any decent results from google.
  I've already tried reinstalling Qt5 (including the creator) but it didn't help.</p>
  
  <hr>
  
  <p>My <code>.proj</code> file looks like this:</p>
  
  <pre><code>TEMPLATE = app
  TARGET = test
  
  QT += \
      core \
      gui \
      widgets \
  
  SOURCES += \
      main.cpp
  </code></pre>
  
  <p>And my <code>main.cpp</code> looks like this:</p>
  
  <pre><code>#include &lt;QApplication&gt;
  #include &lt;QWidget&gt;
  
  int main(int argc, char **argv)
  {
      QApplication app(argc, argv);
      QWidget window();
      window.show();
      return app.exec();
  }
  </code></pre>
  
  <p>And that's all the code I have.</p>
