RUN AS ADMIN.. "Key is already assigned?"

[CydXero]

setting up controls. In the Mapping, when I try to change the button is says key is already assigned...?

 

EDIT!!

I ran the exe as admin. Problem solved.

I ended up deleting the controller and readding it. The deleting of each key didn't work. I didn't try delete and then save.

Was it a key that was already assigned to one of the other players?  I normally delete/unmap all controls, and then only setup controls for player 1.
