Assasin's Creed 3 trainer won't work

The trainer keeps saying it can’t find the game and when I manually select a folder it says this:

I know it is, however. I bought it from steam so I don’t understand the problem. I’ve tried multiple times (different folders, too), and tried the icon thing as well. Nothing works
I need help :sweat_smile:

Oh and ‘help’ doesn’t do anything

Download the update!!!

I didn’t know I didn’t have the latest version. My bad. Thank you, this works
