"QtQuick" The specified module could not be found

I'm trying to compile a project on Windows 10 Pro 64 bit using Qt 5.7 MinGW 5.3.0. but I encounter the following error:

qrc:/main.qml:25 plugin cannot be loaded for module "QtQuick": Cannot load library C:\Qt\Qt5.7.0\5.7\mingw53_32\qml\QtQuick.2\qtquick2plugind.dll: The specified module could not be found.

I've checked the path and the file is there but seems that for some reason is unable to find/load it.

Here is the main.qml:

import QtQuick 2.2
import QtQuick.Window 2.1

Window {
    id: windowID
    visible: true
    width: 800
    height: 600

    minimumHeight: 600
    minimumWidth: 800

    // other componenets
}

.pro file:

TEMPLATE = app

QT += qml quick widgets network concurrent

SOURCES += // list of sources

RESOURCES += qml.qrc

CONFIG += c++11

linux {
    // includes + libs paths
} win32 {
    // includes + libs paths
} macx {
    // includes + libs paths
}

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH += "UI"

# Default rules for deployment.
include(deployment.pri)

HEADERS += // list of headers

The project builds successfully on Ubuntu 16.04 LTS with Qt 5.7 64 bits and OS X El Capital with Qt 5.7 64 bits.
What I've tried so far:

Qt 5.5.1, 5.4.2 and 5.4.0 on Windows 10 Pro 64 bits.
Qt 5.7 and 5.4.0 on Windows 8 Pro 64 bits.
created an empty project with Qt 5.7 on Windows 10 and the it ran without any issues.
copied the file in the build folder but this time it specifies the build path:

qrc:/main.qml:25 plugin cannot be loaded for module "QtQuick": Cannot load library \PATH\TO\BUILD\build-${PROJECT-NAME}-Desktop_Qt_5_7_0_MinGW_32bit-Debug\debug\QtQuick.2\qtquick2plugind.dll: The specified module could not be found.

Are you sure you used 'windeployqt' to automatically handle QML dependencies? I encountered a similar problem because my qml content is embedded in the cpp file. At first, the packaging did not successfully identify the required dependencies. I manually copied the qml directory to the program directory, and then a similar error occurred. If you are in a similar situation, I suggest copying the qml part to a new file (without changing the existing code structure, the new file only allows windeployqt to recognize dependencies), and then repackaging it with the parameter "-- qmldir<Your_Cew_QML_dir>". In addition, if it's just a plugin issue, you can try searching for the qmldir file in the directory where the target DLL file is located, and open it with Notepad to find a similar line:
plugin qquick3dplugin
And delete it. However, after deletion, there is a high probability of other errors occurring
