Yes, I am a Windows user. It seems that Blender has some trouble with Windows OS’s, but there have been fixes in the past. My question: how do I get this shader to work?
I don’t want to hear “do you have it in textured mode”, “did you turn on GLSL”, or “do you have a material or light” - GLSL simply has not worked on my computer. I have even downloaded other’s working files to no avail. Anybody have a fix?
Technical info: Windows 7 64 bit
NVIDIA GEForce 6150 SE nForce 430
Maybe your graphics card just doesn’t support GLSL in which case you’re probably wasting your time trying to get it to work.
The NVIDIA GeForce 6150 SE nForce 430 support shader model 3.0.
Don’t use the original windows driver. The windows driver does only support Direct 3D and no OpenGL.
You must installed the nvidia driver http://www.nvidia.com/object/win7-winvista-64bit-280.26-whql-driver.html.
Don’t forget to choose the right language for the driver.
You may not have the latest graphical drivers, or your graphics card may not be able to handle Blender’s GLSL.
It seems it may be as HG1 said above:)
P.S. Shader model is irrelevant to OpenGL 
“NVIDIA GeForce 6-Series GPUs / NVIDIA nForce4 MCPs
OpenGL® 1.5 Optimizations and Support
Microsoft® DirectX® 9.0 Shader Model 3.0 Support”
Ha ha! Thanks a ton!
That’s probably the last time I’ll let my 'puter auto-update, still a fan of the OS, though.

No thats not correct. For Blender GLSL you need GL_ARB_fragment_shader and GL_ARB_vertex_shader so you need at least OpenGL 2.0 support and the most DirectX 9.0 grafic cards with shader model 3.0 have minimum OpenGL 2.0 support .
And his grafic card has OpenGL 2.1 support.

With PrintGLInfo() it is possible to check if the grafic card supports GL_ARB_fragment_shader and GL_ARB_vertex_shader
