Graphiacll builds problem

I am having a problem with using the builds on graphicall. I have downloaded these ones: and After dowloading them, i opened the blender files. But when i pressed the “Blender Render” pop-down at the top, only two names came, namely Blender Render and Blender Game Engine. The case was with both the builds. How can i solve this problem? I’ve even downloaded the file which was called as “You must download this to make LuxRender work!” but the problem prevails. I have also installed Python 3.2 into the Python folder of the build being installed but nothing happened.

Ctrl-alt-U, go to add-ons, then render, then check the box of the rendering engine you wish to use.
