I can't install game error (The Witcher 3: Wild Hunt)

restarted the install,restarted steam,deleted the game the same crap

there are written Details at the support site of Steam here and treat them))

You error look carefully ... you do not the game is not installed and extra materials (specifically for some reason artbook in PDF, which you have not saved to disk)
Try to jump cancel the extra content (I don't know possible it or not to make the Incentive in Gog versions of games do you usually choose for myself , the incentive is usually I'm not experienced with this so I just downloaded the game and additional materials then I just deleted what would the place not occupied) , check the permissions on the folder ,if not help try to install the game default to the disk (unless of course you drive With SSD it is not a small amount) and then if you installed to transfer the game files onto the disk and re mount the folder (now the incentive is to do)

Someone the Witcher-only sets and some are already 30+ times passed
