I'm sorry I didn't mention the name of the game...my bad.
It is Metro 2033 Redux v. 2.0.0.2 and it is the GOG DRM free version.

Just a FYI for the future.
Every trainer listing should have an information panel below the download option that says:
Example: Stellaris
Game Version:2.2.4
Distribution(s):STEAM
If there isn't another platform, the trainer probably doesn't support it. There are separate listings for other platforms, like on Origin.
For instance:
Game Version:1.06 +UPDATES 64-BIT
Distribution(s):STEAM, GOG, ORIGIN
This is one of the older trainers for The Witcher 3: Wild Hunt. The single trainer was used and usable across 3 platforms.
Hope that helps you going forward!
