When I try to open the trainer it says "how do you want to open this file" and give me other program options. All of windows 10 defender options are off and I did a couple of reboots with no result. I want to play AssassinĀ“s Creed Chronicles: China since it is free for a couple of days on Uplay right now, any idea what should I do?
Try resetting your windows default apps.
