  <p>But I have applied the suggested solutions, and it still doesn't work for me. Relevant information:</p>
  
  <ul>
  <li><p>I use Qt 5.1.0 with MinGW 4.8 32bit for development</p></li>
  <li><p>on my development pc (Win7, 64bit) the program executes just fine</p></li>
  <li><p>I compiled my application in release mode</p></li>
  <li><p>the target pc (Win7, 32bit) does not have Qt installed</p></li>
  <li><p>part of my .pro:</p>
  
  <p>QT       += core gui opengl network xml testlib</p>
  
  <p>TARGET = myApp</p>
  
  <p>TEMPLATE = app</p>
  
  <p>CONFIG += qtestlib help</p>
  
  <p>CONFIG -= app_bundle</p></li>
  <li><p>content of my deployment folder: </p>
  
  <p>myApp.exe</p>
  
  <p>[all dlls, that are in the .exe folder of my development environment]</p>
  
  <p>[all dlls from Qt/5.1.0/5.1.0/mingw48_32/bin]</p>
  
  <p>[all dlls from Qt/5.1.0/Tools/mingw48_32/bin] (including libEGL.dll, libEGLd.dll, libGLESv2.dll, libGLESv2d.dll)</p>
  
  <p>[all dlls from Qt/5.1.0/Tools/QtCreator/bin]</p>
  
  <p>platforms/qwindows.dll</p></li>
  </ul>
