OpenGL install and upgrade


I have some fundamental questions regarding OpenGL in Windows environments.

Do OpenGL have installers similar to the DirectX installers?

How do you upgrade an OpenGL version(for example from 1.5 to 2)?

If I make an openGL application which files do I have to deploy with the EXE in order to make it work on another computer?

Any help would be greatly appreciated!

OpenGL implementation is provided with the graphics card drivers. Meaning, you don’t need to install anything besides the latest drivers for your graphics card.

And really, read the wiki or use the search! This question is asked every second day!
