@@lang_french You could always try this: http://www.majorgeeks.com/files/details/gldirect.html GLDirect, I had to use it to get JKA working on my old laptop, and this one. I got the same error as you, couldn't load openGL subsystem. I'm not on windows 10, so I'm not 100 percent sure this will work, but you should give it a try. It's what I've been using for years now. Just install it and it should automatically be using GLDirects version of openGL. Let me know if it works.
