you guys that obviously can not patch by hand use the
eqemulauncher, it will automaticly patch for you so you dont have to worry where to put the files or if you need administrator rights to overwrite them etc.
the eqemulauncher only requires you to have ZIP (included in windows since XP) and .net framework 3.5 (included since ... vista? i think, in win7 definatly included)
