Canon seems stuck in the stone ages... You can only install their software from CD. There is no downloadable full version of their DPP software anywhere! All their updates will only work if the software is already present. I don't have a CD ROM drive in either my mac pro or my MacBook Air (can't remember the last time I used a CD - maybe to install Snow Leopard back in 2009?)... WTF Canon! Am I the only one?
