Yeah i installed 4.5 and it still doesn't work. I run the trainer and F1 starts it (game running) but none of the numberpad activations work

Are you at the main menu or actually in game when you hit F1? You should have actually loaded up a world and be in it when you do. Also, are you hearing "Trainer activated" twice? When you hit F1 and hear it the first time it is scanning the game code. It will say "Trainer activated" again when it is ready to go.

This is an interesting point you figured out and it explains a lot. Thank you very much Sir, I'll keep an eye on this.

THAT DID IT! Thank you RobSmith176 you are a sir!

damn i was trying with framework 4.5 and when i read that use F1 in game i got trainer working. Really nice to have people who actually figure out things and more so that they do post here on forums

Just point out here as well as in the trainer post. This fact apparently means that the trainer page needs to have system requirements updated, seeing as how no one using XP can use it. .Net 4.5 won't install on XP, only on Vista and later.
