If you get the error message “graphics card’s OpenGL version is 2.1. SketchUp requires a graphics card that supports OpenGL 3.1 or better”
Then probably you can fix it by downloading one dll and putting it in the folder of the sketchup executable.
download dll from here: https://fdossena.com/?p=mesa/index.frag
Extract opengl32.dll from the downloaded file. Save it in the same folder as the .exe you use to start the program that needs OpenGL 3 support.
Run the program to see if the problem is solved.
The solution worked great for Sketchup.
