topic i cant find where to download it
You can find an OpenGL SDK on NVIDIA’s or ATI’s website, depending on which brand of card you have. Make sure you’ve got the latest drivers for your card at the same time.
yuk Nvidia but ill try it any way and i have vista so it shouldnt hurt my comp rite?
An SDK will never hurt your computer.
Video drivers might, but if you need the more advanced features of OpenGL you might not have a choice there. Windows only ships with support for OpenGL 1.1. Of course, if you bought your machine with the graphics card preinstalled, who knows what drivers they gave you.
BTW bobobo, do you want to program OpenGL ? Or run OpenGL games/tools ? In the second case, all the GL you need is provided by the appropriate video drivers fro your card, go for nvidia.com apparently.
i would like to run cuz u see im trying to play a game called SoS by the company outspark and to see the graphics i need OpenGL 1.2 or higher and ive been lookin 4 ever
Do as we told you.
Find your driver here, and install it :

And learn your own language 
well i just tryed it and it said i dont neeed to download any drivers but the grahics arent working i think i still need OpenGL sigh, this is so hard
No. What you have presently is probably the crappy Microsoft driver for your card. You really need the driver from nvidia.
What are :
OS : vista : 32 or 64 bits ?
video card : ?
Install this driver :
