  <p>I wanted to debug my code, It compiled successfully, But runed with an error (return value -1073741521):</p>
  
  <blockquote>
    <p>Starte D:_work_\applications\my_app\debug\my_app.exe...Das Programm ist abgestürzt.
    D:_work_\applications\my_app\debug\my_app.exe beendet, Rückgabewert -1073741521</p>

  <p>I think it is not a problem of the application, because I've tried to create an empty project and debug it, did not work as well.</p>
  
  <p>I have installed the same Qt version on the other PC with Windows 7 running on it, and there everything worked without a problem. </p>
  
  <p>Any ideas what could cause this problem and how can If fix it? </p>
  
  <p>ps. If any important info is missing, Please let me know and I'll try to give it.</p>
