Now I have uninstalled and reinstalled the NVIDIA driver, connected the 3rd screen directly to the graphics card (no switch) and added the cloudcompare.exe again to the NVIDIA system control for handling the OpenGL with the GPU. Nothing helps, same error "...at least OpenGL 2.1..."
Additional I tried the same on my render machine. It is a AMD Threadripper 2990WX, but only an old GTX 550 Ti (as it is only my rendering machine). Here I also configured cloudcompare.exe in the NVIDIA system control to use the GPU. In that case cloudcompare doesn´t even start with any error message. In this case OpnGL is Ver 1.1 with the latest possible driver (2019). So it would´nt work, but should´nt I get here an error message like "...at least OpenGL 2.1..." also?
Error window: OpenGL 2.1 needed - I have 4.6

Can you check that your opengl actually works, if yes then the issue inside cc, if not i suppose it is unrelated to CC.

What Os do you have exactly. And which driver?

Open GL Extensions Viewer says:
OpenGL:

Driver:
551.61

I tried also to install older versions of CloudCompare, all had the "The application needs OpenGL 2.1 at least" error

I was curious about if your os might be a "N" version without media pack.
With the driver, i meant to ask which branch are you using, studio/new feature branch.
Have you tried to launch any other app which known to use opengl? First one comes to my mind in this field is autodesk recap.

Hello HeadLess,
this was the crucial clue: When I started ReCap I also has an error message regarding the graphics system. It was "Termianl Error Initializing Graphics System Code RE3102" Autodesk has a solution for this:
https://www.autodesk.de/support/technic ... ReCap.html
It says to delete the two Environment Variables:
Variable: QT_OPENGL - angle
Variable: QT_ANGLE_PLATFORM - d3d9 (in my case)
After doing that Recaps and also CloudCompare was starting without error!
In my memory the QT variables were set in connection with installing VRay some years ago. But also without these variables VRay is starting.
Thank you so much!
