Alright so I finally got into a little 3D stuff for a buddy of mine. It was a nightmare trying to find a collection of these files that all worked together. Now my new problem is most guides online show how to use blender 2.6+ but i'm stuck with 2.49b.

Does anyone have a collection of these 4 pieces of software as update as possible and still work together?

i use Windows 7 64bit.
