    Hi and welcome to devnet forum

    Similar as to your previous question you need to give more information about your actual problem.
    What compiler are you using?
    Also it would help to provide source causing the problem.

    Vote the answer(s) that helped you to solve your issue(s)

          Which of the default projects are using?

          I have created the stack qt quick project and I can open the designer with the qml.

          Which version of Qt creator are you using?

                  Best is to create a new Qt Quick project. Compile and run as is to verify that it is properly created. Then try to use the designer on its .qml files. As indicated above, I have tried the application Stack
                  5b928d37-b593-4171-883e-8483d6b9dc14-image.png

                  It should work with this project.
                  If not, you probably have a problem with your installation of Qt. Remove and reinstall the open source version completely.

I use the emulation layer given by Qt nothing works I even use the puppet nothing always but in revenge I noticed that my path was empty in the .pro file. should i add some path? I am waiting for your response thank you

                                      Hey koahnig,

                                      thanks.

                                      I have been working with Qt 5.9.0 for a while but I've never really used the Designer in QtCreator.
                                      I wanted to try the Designer in 5.9 but that didn't work, with the same.
                                      So Yesterday I installed a completely fresh new Qt 5.14.1 with the online installer and I tried the "heartrate-game" and the "gallery" example but this didn't work either with. I compiled with msvc2015 64 bit and i can also start the example, but the designer doesn't work..

                                      I already tried with some other paths that i found as solution but nothing really fixed the problem.

                                      Thanks for you help.

                                          That is in my creator. However, I do not think that I have ever touched the setting.
