    Hi everybody, i am new to Qt development., Just recently installed the latest version of Qt 5.14.2 + VS2019 Pro (Windows 10) . I can run the examples inside the Qt Creator without any problem, but cant deploy the examples using windeployqt.exe... I did everything like in this video instruction: https://www.youtube.com/watch?v=gnpPosTbttM&list=PLQMs5svASiXNx0UX7tVTncos4j0j9rRa4&index=3

    but after deployment procedure .exe just doesnt start (no errors and no GUI is shown up) . I tried diiferent examples (dashboard, quickGamepad, automotive and so on.. behavior is the same cant start exe outside of Qt Creator)

    Help me please to find a solution...

      You are using Qt Quick, you need to use the --qmldir and point it to the folder containing your application qml files.

          Hi and welcome to devnet,

          What exact example are you testing ?
          Qt 32 or 64 bit ?

            Try to run the .exe from command line (cmd.exe) and see if you get any warnings or errors printed.

                  How did you call windeployqt exactly ?

                  1. Copied automotive.exe (release) to new folder called "Deploy"
                  2. Run the Qt command prompt "Qt 5.14.2 (MSVC 2017 64-bit)"
                  3. Here is my console output:
