I am lost when it comes to this. A statistician asked that we install this on their computer, but I have not the slightest clue if I am doing it right or not, I have done research on UNIX commands and all that but I am still lost. Do we need to use the source code if we download the installer, or do we need both? The instructions were very confusing to me too. We are trying this on a Windows 7 x64 machine.
