How to install QT VS Tools add-in? What versions are most stable?

mikeitexpert

I am struggling to get QT VS Tools installed on my machine. However, I can't get VS 2015/2019 to recognize my QT installation (from QT VS Tools | Qt Options ).

I have tried VS 2015/2019 Community Edition.

Though, I am not sure why the QT installations (namely Qt 6.1.2 & Qt 5.14.0) are not added to the list as I do below steps.

FYI, I tried different versions of the QT VS Tools add-in

qt-vsaddin-msvc2015-2.5.2-rev.01.vsix
qt-vsaddin-msvc2019-2.5.2-rev.01.vsix
qt-vsaddin-msvc2015-2.6.0.vsix
qt-vsaddin-msvc2019-2.6.0.vsix
qt-vsaddin-msvc2019-2.7.1-rev.18.vsix

For one thing, I need to know what is the best installation order to get things to work properly.
What QT version(s) is/are most suitable for VS 2019/2015 integration?
What QT VS Tools versions are more stable?

I also get an error message in the VS Output Window which I will attach below shortly.

Much appreciate your valuable comments.

There is no answer to this, does this mean it is a rare issue?

I have VS Pro 2022 and see the issue there.... 7 years on.
