"QtQuick" The specified module could not be found

[athan_david]

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.
