hi guys, when i want to install the witcher 3 it says : Installation failed with code:-3: Checksum error Please restart and try again.
i've tried it a couple of times now and it always crashes at the same time. you have any tips?

i will also add to my question is that i cant seem to download it with galaxy, since i've gotten the game free with purchase
of my nvidia graphic card and galaxy will only let me purchase the game
