    Then you should use that --qmldir option to point to your QML sources.

        Hi
        Do you have more versions of Qt framework?
        If yes, are you sure to run right windeployqt?
        Always if yes, Check Qt DLLs that must be aligned with your application.

          please post the argument you used for the tool, I think you did not add the actual path to your qml files after adding --qmldir

            Hi,
            I reproduced your issue.
            I run windeployqt with debug application.
            Is possible your application is in debug compiled?

                  @cupressus
                  Try running a dependency walker (https://www.dependencywalker.com/) on your .exe to see if you can spot any potentially missing/not found/wrong bit-ness DLLs on the target system. Also if you are not already doing so try running your executable from a Command Prompt rather then double-clicking it, Windows might be outputting some kind of message which you could see there.

                    Hello, have a look at the attached picture. This is what dependency walker shows.Unbenannt.jpg

                      I have found the error. I did a mistake specifying the path to qml files. Now it works.
                      Nevertheless i am wondering that there ar so much files needed for this simple app.
                      125mb?

                        @cupressus look at that, had you done as I asked

                        please post the argument you used for the tool,

                        we might have been here earlier.

                        The files will be big, OpenGL.dll will be 20 mb is alone.
                        That said 128mb is a lot and more than I would expect, but without more information hard to tell/advice

                          here the command line i used for deployment:

                          windeployqt --qmldir c:\qt\5.14.2\mingw73_32\qml c:\myApp\myApp.exe

                          Yes i can delete some files step by step and look what happens but i cannot imagin
                          if there is not another way.

                            ah, an error that I expected, you gave the tool the path to the whole QML folder of your Qt installation therefore it got everything qml related -> your folder is so big now.

                            That path should be to the top most folder of your created QML files.

                            Lets assume, your top most QML File is named MySuperAppMain.qml and it has the following path c:\MyQtProjects\MySuperApp\MySuperAppMain.qml

                            than your argument should be:

                            --qmldir c:\MyQtProjects\MySuperApp

                              @J-Hilk , thanks that helped. The installation folder is now a bit smaller but still
                              97mb.

                                    @Samuel-Alves Hi and welcome to devnet,

                                    You have to give the path to your qml sources. The ones that you have in your sources not the one from Qt.
