title: Serious issue with starting application in QtCreator
body: <p>I have been writing an application for two years in QtCreator. (My application uses some external libs).</p>
  
  <p>Recently I've ported the application into Qt5.3mingw(windows7). The application built successfully but failed to start within QtCreator and gave "The program has unexpectedly finished.".  </p>
  
  <p>With debugging the application, it gives this error message: "During startup program exited with code 0xc0000135".</p>
  
  <p>However the application starts succussfully outside of QtCreator! It seems the QtCreator has severe problem in starting the application or it's the linker problem. </p>
  
  <p>I've even uninstalled all Qt and QtCreators and re-installed them, but the problem insists.</p>
  
  <p>Any guide will be appreciated. Thanks.</p>
