I've noticed that since I've upgraded to Win10 from Win7, the F1 key no longer works in DA:I. I can close the game and hit F1 and immediately get that the trainer cannot find the game. But when I'm in game, I hit F1 and nothing happens. Is there something in Win10 that turns off the F1 key in game? If so, how do I shut the bloody thing off?
I've used the DAI trainer on windows 10 and haven't had any issues with it. Other than the usual troubleshooting (Run as admin, make sure your firewall/av isn't blocking it etc) I can't think of what might cause that issue. Have you tried running the trainer AFTER you start the game? Some people have also recommended a reboot, but that could just be coincidental or snake oil.
