Well I clicked the "Download Latest Version" link and I downloaded the file. When I clicked to run the file it brought up mass effect 2. I had the option to play mass effect two and I could unistall it. I also noticed that the icon for the installer was mass effect 2. Now i'm either going crazzy here or there is some sort of a problem with the EIR installer.
Sometimes if windows is slow for some reason, it will take an icon of a installed or recently installed programm and use it instead (just so it looks the same) when double clicked will still run EIRR
