    Hi,
    I've installed the Qt OPC UA module. I can run the Viewer example without any problems in Qt Creator, but if I delpoy the application it shows the error message: No Plugin available.

    The example is deployed with windeployqt, I also copied the open62541_backend.dll from the plugins directory to the application directory manually .

    My Steps:

    git clone https://code.qt.io/qt/qtopcua.git
    cd qtopcua
    git checkout 5.13.1
    qmake
    nmake
    nmake install
    

    Why does the example run in Qt Creator and not after deploying?

      @beecksche Have you run your app with the environment variable QT_DEBUG_PLUGINS set? That will print additional messages and could indicate what goes wrong.

      Regards

      Qt has to stay free or it will die.
