      @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

                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

                      @cupressus I used the same commando to deploy my application but when i try to run nothing happens.

                      The command: C:\Qt\5.15.2\msvc2019\bin\windeployqt.exe --qmldir C:\Qt\5.15.2\msvc2019\qml C:\Users\Samuel\Desktop\deploy\main.exe

                        @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.
