    Description

      Hello,

      I'm developing a webEngineView with QWebEngine. But when it opens, I have the following message in the console:

      And I try the sample QML application. I have the same message in the console, and the app crashes.

      import QtQuick 2.0
import QtQuick.Window 2.0
import QtWebEngine 1.0

Window {
    width: 1024
    height: 750
    visible: true
    WebEngineView {
        anchors.fill: parent
        url: "http://www.qt.io"
    }
}

      Does this mean that QWebEngineWidget can't be used in windows 7 ?

      Thanks
