Grim Dawn Message Board  

From your Steam library, right-click Grim Dawn -> properties. On the General tab click Set Launch Options then type /x64
click ok->retry game now.

Just for info.
The game has been updated to version 1.1.7.2, but the current trainer (1.1.7.1) still appears to work (I've not run all the options but at least the 6 I tried, do: Inf health, mana, super run, super fight, potion and spell cooldowns.
I didn't report this in the proper notification system as I didn't think it warranted it.

What is aob? Where can it be found? Can it be downloaded?

AOB - array of bytes, found inside games code, it's a range of addresses the trainer scans to find the correct value to make a cheat work.

Here is what is happening when I try to run the trainer.
I am running the 64-bit version of the game and the trainer.

Information: 0 : Grim Dawn, 1.1.8.0 64-Bit, STEAM/GOG
Information: 0 : Trainer version: 1.133
Information: 0 : Trainer is up to date.
Information: 0 : Attaching to process: Grim Dawn
Information: 0 : Successfully attached
Error: 0 : getplayer: Cannot find aob!

What is the array of bytes that the trainer is looking for?

Reboot PC to clear excess memory, get a fresh copy of latest trainer, run trainer as admin, read the instructions and try again. At times, a new game may be needed to resolve failed options if the data in your save file was altered. Use on a new game and test the option. If it now works, quit to main menu and load your save and try it again.

I did everything you suggested I do. Followed your directions to the letter. Still no good. Trainer crashes out immediately and gives me the same error: Error: 0 : getplayer: Cannot find aob! I am at my wits end on getting this to work, since I am not a programmer. Thank you for all of your help and suggestions. The trainer, without a doubt, has a bug that needs to be fixed. I will play the game without it until it is fixed and works properly.

Out of curiosity is steam launching the 32-bit version or the 64-bit one and do you have the DLC installed? Trainer will only hook to the 64-bit exe.
