    @shravani Running outside from QtCreator is different. You actually only need to copy your qmqtt.dll if you want to run from QtCreator. If you want to run outside of QtCreator you need to deploy your app as @SGaist already said. In one of my previous posts in this thread I posted a link to a side where you can read how to deploy your app on Windows.

            @shravani When you built qmqtt.dll were any other DLLs created in the same directory? Did you try to find out what is missing using http://www.dependencywalker.com ?

                @shravani Then you should deploy your app using Qt Windows Deployment Tool and see which DLL will end up in your deployment directory.

                      @shravani Should be possible if you have Internet connection and access rights.

                          @shravani I never used it but I guess you need access rights to connect? You should ask the people providing those brokers.
