Zoom function when using the mouse wheel is in reverse when i use X7.

Zoom function when using the mouse wheel  is in reverse when i use X7. On X4 when i push the mouse wheel forward it zooms in  (makes the image bigger) however it is opposite on X7 . Can i reverse the action of the mouse wheel on X7. tried to adjust mouse settings on PC, Tried mouse settings in X7...i CANNOT seem to adjust the direction . I AM USING THE SAME MOUSE in both programs.

Any suggestions
