@SGaist Yes I installed the for VS2013 and 2015 also. I'm also installed VS2015 application, but after the QT.

Just so we are very clear on this.
The Qt Vs201X kits do NOT work with mingw.
You must also download the full vs 2013 or 2015 COMPILER from microsoft
and switch to that full compiler. So Besides the Qt kits, you should also have installed
the actual compiler. as its not included same way as mingw kit.

Initial searching for a solution on the web shows this has been a problem for a number of years.
QTBUG-43614 webenginewidgets examples does not build on Windows
https://bugreports.qt.io/browse/QTBUG-43614
QTBUG-44108 webenginewidgets examples does not build on Windows (second try)
https://bugreports.qt.io/browse/QTBUG-44108Both of the above QTBUG items are marked as closed. Obviously they are not.
Yes..I have QT += webenginewidgets set in the .pro file.
Windows7 Pro SP1 32 bit OS. Creator4.2.0 Qt5.7.1. from this download..
qt-opensource-windows-x86-mingw530-5.7.1
The exact same project built on OSX using Creator4.2.0 Qt5.7.1. compiles and runs properly.
Do I need to download and install BS compilers from Microsoft to get this to work? If so, do I need a different Qt download in order to use the MSBS compilers??
Do I need to upgrade to a different OS..Win8 or Win10? Or Maybe Win7 Pro 64 bit??
Is there a solution for Windows7 Pro SP1 32 bit OS??

The QtWebEngine platform notes explain what is needed to build the module.
QtWebEngine is using the Chromium project as backend so it depends on what platform they support. If you would like to have a MinGW build of QtWebEngine then you should rather push this to the Chromium project.
On a side note, there's @Konstantin-Tokarev QtWebKit reboot project that might interest you.

I am now using: qt-unified-windows-x86-2.0.5-online.exe...and have a current Commercial License for Application Development..all handheld and desktop environments are covered.I tried installing Qt5.7.1 for MinGW but there were no QtWebEngine libraries.
I tried installing Qt5.7.1 for MSVC2015 and it had the QtWebEngine libraries, but no compiler.I am now re-installing 5.8, 5.7, and 5.6. Maybe one of those will have the libraries I need.

Thank you for all your work. its a huge task for a beginner to build webkit so your project
is very welcome. -

Also credits go to Vitaly Slobodin and other contributors of revived QtWebKit, who contributed lots of patches enhancing Windows and macOS support. Without them, it could happen that only Linux would be supported.

A real ancient version of WebKit I was using in Qt4.7.2 did not...which is what has prompted my attempted upgrade to Qt5x/WebEngine.

Like written in the documentation I linked, QtWebEngine is not available with MinGW for the reason I have already given.
As for Visual Studio, yes, it's up to you to install it. It has always been the case. Microsoft doesn't allow any third party to bundle its development suits.

You need to install Qt 5.8.0 and extract QtWebKit binaries that you can download from link that I've posted above.

https://github.com/annulen/webkit/releasesI am still using the qt 5.5.1 mingw version, and using the default webview in that QT version. One BIG problem I met is memory leak seems still in qt 5.5.1 mingw version ...
Is the memory leak problem resolved in the qtwebkit-tp5-qt58-mingw530-x86.zip or qtwebkit-5.212.0_alpha2-qt59-mingw530-x86.zip from https://github.com/annulen/webkit/releases ?
