Obviously someone is using the trainers for Fallout 3 and Thief (2014)… so someone must be making them work. However, when I use them, WeMod simply tells me that the game is loaded in 32-bit and the mod is in 64-bit, and then the mods don’t work. What’s the work around?
Hello and thank you for reaching out. 
Refer to this thread for the troubleshooting specific to this issue: "These cheats were made for the 64-bit version of the game, you are running the 32-bit version" - #2 by Ravenfyre.
