Hey Guys i bought The Witcher 3 GOTY Edition on MMOGA and used the key in GOG (it was an special GOG Key). After download the game my pc say :"This app can´t start on this PC"

So i can´t even start the game. On my Pc is win 10 running and ive got the specs to play witcher.

So do you guys have any solutions ?
