Register first. Go to the download section. Xbox Utilities. Page 3 then look around for which version you want.
instead of looking for Evo-X then looking for all the other programs your gonna need to make backups of games and stuff. just go to http://slayer.xbox-scene.com/ and get there auto installer. it's got pretty much everything you'll need. But if you do get then afterward you should get onto Xbins and get a newer version of DVD2Xbox.
