Not work for the new DLCGuys it works just fine with the latest update!
If you have it on Steam like me here is what you do.
1. Open the trainer first (run as Admin)
2. Open steam Library and right click on 'Sins of a Solar Empire" and select Properties.
3. Open the Local Files Tab and click on "Browse Local Files..."
4. Now that you opened the game folder just left click on the "Sins of a Solar Empire" application/exe (NOT THE DEV!)
5. Lastly, enjoy! All cheats are tested and accounted for, all works fine!
