My OS is a 64-bit one. How to find out the installed OpenGL version ? Wouldn´t a check in the game be a good idea?
Well, you will probably have an app installed in your computer to control the graphic card on your computer. Find that program or you can try to install OpenGL Extensions Viewer. It is an app that i know. Check the opengl version in C++ could be an idea to solve these kind of problems. Concretly, I use the OpenGL 6.14.10.13440 version.
