    I have uninstalled QT5 and then reinstall it.

    QtCreator is working ok.

    If I run a project through QTCreator, it runs without problem.

    But, if I go to the debug or release folder of the project and run the exe directly, it doesn't start and shows a message box telling me that Qt5Widgetsd.dll is missing.

    What is happening? Is this something related to paths or something?

    Thanks in advance for you time and invaluable help.

      have you added the .dll files into your app directory? If not, you should add them.

        I'm sure your response is the solution, but I have put the dll directories in my PATH and it worked too.

        Thanks, Code_ReaQtor!

          Though it works, adding them into the PATH is not the recommended way if you have more than one Qt version. Things might get messed up and conflict might exist.

                    Hi and welcome to devnet,

                    When running your application directly from explorer, you need to do the same step as you would for deploying it on another computer. Here is a fine wiki "entry":http://qt-project.org/wiki/Deploy_an_Application_on_Windows on the subject.
