using OpenGL 1.2 stuff

I have a question. I want to use 3d textures in my program, which I know is implemented in opengl 1.2. However, I am compiling with the original opengl 1.1 that came with msvc++. Do i need to download a different sdk to make use of 3d textures? or should things be fine with the gl 1.1 files?

thanks!
