Hi Jason, which command line arguments did you use in windeployqt, which directory structure does your application have and did you add Qt paths to the environment of the command line before running windeployqt? I know that the documentation for windeployqt was quite obscure last time I checked, especially regarding the deployment of QML applications. You should especially pay attention to specifying the path to your application's QML files so that windeployqt can resolve the dependencies. In the resulting deployment you should get the compiler/C/C++ runtime (like libgcc.., libstdc++... in case of MinGW; msvcrt...something in case of VC++), Qt dlls (like QtCore, QtGui, QtQuick, ... and whatever your application is using), a subdirectory with platform plugins (this will probably be qwindows.dll) and (important) a lot of subdirectories with QML modules even with those that your application does not use explicitly. If you double click the application or start it from the console and nothing happens, you should look into the task manager: if the process of your app is running but you see nothing then the QML part of the application probably has a fault. Mostly this is because of import paths or windeployqt being unable to resolve the QML dependencies correctly. You can also debug it by building your application with CONFIG += console, in this case, you will get a terminal window with QML errors if this is the case.
