I have autocad 2009, I was sent a file made from a newer version, so I downloaded a viewer, but when I try to open it, it says I need "net.4" not sure waht that is or where to get it. I did all my windows updates (Using Windows 7, 64 bit) thinking that was the problem, but I stiil get the same "net 4" error. Does anyone know what this is & how to correct it?
