I succeded to solve my problem with Autokey program (do a google search)
Configure your mouse as a right-handed user -important-, then install Autokey, and use this script to switch from right to left handed player -with Ctrl+Alt+L- :
I can now play with all my XNA games (CoH, terraria, War plan Pacific) as a "REAL" left handed player
I have severe Carpal Tunnel's in my right elbow so that even though I am right-handed, I have had to learn to use a mouse with my left hand. The above works to switch the buttons but in Windows 7, there is a specific setting under Control Panel which allows you to do the same thing.
However, NEITHER work with COH. Even if the mouse buttons are switched using the above or using Windows control panel, COH will not recognize the switch.
That's a shame because COH is the ONLY game in which with which I have this problem.
So for me, if there is no fix, my options are: 1) learn to use the mouse with my left hand but with buttons configured for a right-hand player (certain to be cumbersome, since no other game makes me do that); 2) play the game with my right hand and suffer pain; or 3) move on to something else.
