How do you get MW3 for PC to work with xbox controller?

[size=20]so my xbox was banned so i switched to pc today and really dont like pc controls for games like call of duty so im trying to use an xbox controller and i hate xpadder, and it says that MW3 supports xbox controllers but idk how. there isnt a console to open up or at least i cant find one so i cant type exec default_controller.cfg or whatever so is there another way?

I tried this yesterday with AlterIW. It is the hardest thing ever. I have no idea. I even bought a controller for PC and I can’t get it to work.

Why do you hate Xpadder. thats what i would use if it did not work natively.
I can get you the latest version of xpadder for free. I paid for it.

When i plug mine in it works automatically. if it doesnt work like that xpadder is really easy to use.

It should work instantly. When you plug the controller in does your pc say the driver is installed?
Anyway you should get use to the pc controls because you will get out classes.
