    I'm doing:

    @
    QProcess starter;
    starter.setWorkingDirectory("C:/folder/");
    starter.start("C:/1.exe");@

    And it doesn't launch the C:/1.exe file, which exists and launches fine with @QDesktopServices::openUrl(QUrl::fromLocalFile("C:/1.exe"));@

    The latter doesn't allow for working dir customization, so I really need QProcess to work. Advices?
    P. S. This is on Windows.

      Hi,

      Where do you use the QProcess code ?

      if it's something like this:
      @
      void MyWidget::myFunc()
      {
      QProcess starter;
      starter.setWorkingDirectory("C:/folder/");
      starter.start("C:/1.exe");
      }
      @

      start will get destroyed because it gets out of scope. So 1.exe will get killed.

      Have a looked at the QProcess documentation, the different methods are explained.
