argl error: Your OpenGL implementation and/or hardware's texturing capabilities are i

Hello,
I am beginner of ARToolkit .I configure opengl on my windows 7 pc .Program work fine.but when i draw a rectangle then show this error.
How to solve this error.Please help me

“argl error: Your OpenGL implementation and/or hardware’s texturing capabilities
are insufficient to support rectangle textures.”

See the upper-right box at:

Looks like you need to install OpenGL drivers that support at least OpenGL 2.1 (assuming ARToolkit will use texture rectangles in GL core). If not, you at least need texture rectangles in extension form (if ARToolkit supports them as an extension).
