Ghost Recon: Wildlands comes with an Anti-Cheat System called "Easy Anti Cheat".
This prevents trainers from finding or get access to the desired process of a game.
So follow these steps to get the trainer working.

Make sure the game is not running. If its running... Exit the game.

Now go to your installation directory of Ghost Recon: Wildlands.
There you can find a folder called "EasyAntiCheat".

Make a backup of these files:
EasyAntiCheat_x86.dll
EasyAntiCheat_x64.dll

Overwrite the files with the ones from the archive (EAC Bypass).

Now you can play with the trainer...
