OK thanks, I will give it a try, but I must say this is well beyond my knowledge level of how this stuff works. I was a hardware engineer and only occasionally dabbled in software. At this point, it's really not that important as I will be replacing the computer anyway.
So that got rid of the OpenGL version complaint but there are other unrelated problems. I installed qtpyvcp exactly according to
qtpyvcp.kcjengr.com/install/quick_start.html
and get the following:
