I am experiencing errors after installing QGIS using the Osgeo setup file

This happened on a second windows 10 machine (first on a laptop and then

am not new to UI's in C++ as i have done several
more complex ones before.

I was upgrading a c++ plugin that I had used in the past and almost
eliminated all the the usual compiler errors due to version changes
according for the current version (3.6).

work. Also Q
Is there anything else that changed between 1.7 and 1.9 on installing C++

In the past, I used to be able to copy the dll to the plugins folder and then
