Just so you guys know, this is a permanent change. I got everything to work with the EAC file, but I can't go backward to an unchanged EAC file setup. I did the initial part and used the trainer, also used cheat engine just testing. Then I removed the altered files and put the backup files back in.
The game says that there is an untrusted file steam_api64.dll and won't run. I deleted all the altered ones, plus this one, and verified. Steam said it was fixed, but I continue to get this error and can't run the game. I actually CAN run the game if I go back and make all the file changes to get the bypass. So I will do this and hope Ubisoft doesn't detect this stuff down the line and ban me.
Just as a heads up, it seems to be a permanent change to your files.
