I ended up being able to play, along ubisoft support has to answer when a uplay?,
it appears that a proc intel E8500 is not enough .. the gtx 760 card is suitable but with the proc E8500 it did not work ;;
everything works with the 4690K and GTX 760 card ..
for farcry4, super game can play .. unlimited hours or even more beautiful landscapes, playable bug .. I recommend it to those who loved farcry .. but the missions are longer and more varied, field game is great and varied, vehicles, a small helicopter very convenient for travel in the mountains ..
attention to animals including eagles and voracious fish without stops put you in more danger than humans ..
in easy mode you can finish the game solo,
good game
