Halo: The Master Chief Collection Message Board  

Download the correct trainer for your game. Scroll down the list of trainers until you find the one marked as Halo Reach.

So there is different trainers for different aspects of the Mast Chief Collection? Wonderful

Yeh, a real inconvenience.

I really appreciate the trainer for this game. And I can tell that additional work had to be done to make it work properly - it does work well. 🙂

Guys, can this be used to unlock achievements?

Thanks,
Vicky

AFAIK, only Steam version work, but you need to use the included "steam launcher" and have the trainer file in the same directory of the game folder. It's work for me.

Halo 2 Trainer worked this AM, tonight it won't launch at all. Other Trainers I have work fine. I removed this trainer and re-downloaded the Halo 2 trainer with still no luck, Rebooted my computer and again this trainer refuses to launch.

Trainers and launcher for all of Halo MCC games have to be added to the exclusion list for any security software. It will register a false positive and quarantine them, especially the launcher. Delete any files in

C:\Users\USERNAMEHERE\AppData\Roaming\Cheat Happens\0x90\
C:\Users\USERNAMEHERE\AppData\Local\Temp
C:\Users\USERNAMEHERE\Cheathappens\Work

try again. Just tried mine and it works fine.
