So you make a shortcut to C&C3's game executable on your desktop, and add -win behind everything on the shortcut's "Target" line.
I believe in Origin you can give that in the "launch options" field.
Tried that, It no longer works. Best guess, because someone at EA decided to prevent that, because they felt it was tampering with the program. But that was over a year ago, since then I have not been able to get any game from EA to work, and their only response to my support tickets is "We are looking into this, please be patient" then after 3 weeks, they just abandon the ticket, forcing me to file a new one.
