title: InnoSetup is not restarting the closed applications
body: <p>I am working on an installer by using InnoSetup 5.5.6. Application is an CLR Windows forms application compiled with VS2013. Installer and application works succesfully. However, I wanted to check the behaviour of the installer when the APP is running. As mentioned in innosetup documentation installer warns user about the running application and says that it will close it and attempt to restart it.
  It closes the application succesfully and completes the installation but the application is not restarted!</p>
  
  <p>I tried /RESTARTAPPLICATIONS argument already but has no effect!</p>
  
  <p>Any suggestions or hints that I can follow?</p>
  
  <p>Here is the log:</p>
