The game has not been updated since 2012, as far as I can see. So the trainer should be working fine as long as it is legitimately purchased from a store that we have a trainer for.
- If you got the game from Steam, use this: Dragon Age II Cheats and Trainer for Steam.
- If you got the game from Origin, use this: Dragon Age II Cheats and Trainer for Origin.
- If your game is cracked/pirated, there’s nothing we can do other than advise you to buy it properly.
Also make sure you are following the cheat instructions correctly. If you hover your mouse cursor over the “i” next to the cheat, there are instructions there on how to use it.
