    I need your help to solve the problem. I use Qt version 5.7 msvc2015_32 on windows 10 64 bit. I create a standard QtQuick.Controls2 application in release mode. After I have completed all the required actions to deploy with windeployqt.exe I still can't run the application. It does not display any warnings about missing dll , but the process hangs and there is another process Runtime Broken that I see in task manager in windows. Does somebody know how to solve this problem?

    @smartcoder.v.arch Does it work if you start your application from QtCreator/MSVC?

      Also, if you start your app from a CMD window, do you see any error messages?

      BTW the process name is "Runtime Broker" and not "Runtime Broken" and it's used to launch Modern/Store apps, so it should not matter for your app.

            @hskoglund Hi! I tried to run an app in cmd.exe - didn't get any output. It seems like the process stopped immediately...((

              For me windeployqt didn't copy all necessary files, see https://forum.qt.io/topic/72642/deployment-on-windows-app-runs-but-doesn-t-show/2. Have you tried debugging the deployed app?

                @Eeli-K Maybe I'll try to do it manually. Thanks

                    Note
                    Make sure that .exe file is not called ANYTHING with "update" in it.
                    Win 10 might block it silently.

                        Thank all for your help. I've solved the problem - copied the folder C:\Qt\5.7\msvc2015\qml\QtQml , C:\Qt\5.7\msvc2015\qml\QtQuick , C:\Qt\5.7\msvc2015\qml\QtQuick.2 and the app run!
                        I understand - there are a lot of unnecessary info but I have no time to explore it.
                        Thanks a lot!!!

                          Guys, I understood the deploy QtQuick.Controls2 application on windows. It's so simple - I had to implement only 2 steps. Step #1 - - windeployqt --release --qmldir <path to your project dir whith qml files> <path to bin.exe> , after that to add MSVCP120.dll and MSVCR120.dll (It depends on which version of msvc you use) in the folder with .exe file.
