Recently I have been trying to install Snow Leopard to no avail. First, I attempted to install it from the dual layer disc I have, and when that wasn't working I partitioned my external hard drive and created an installation image from which to boot. I keep receiving the error: "installer could not copy the necessary support files" I have scoured the web trying to find the solution, and most people have pointed toward a hardware problem. I verified the HDD and I played with the RAM configuration. Rember reported that one of my 1gb modules was faulty, so I took that out and I still keep getting the same error. Does anyone know how to get around this? It's driving me up a wall.
