Hi i can get my rise of legends to run in compatibility mode xp service pack 3, but when the game boots up my mouse curser is frozen, although it runs in the background. i cant play the game as i cannot see where my mouse is pointing. The same problem occurs with rise of nations, but none of my other games. I am running win 7 home premium 64 bit. My mouse is a4tech x7. my system is an i7 2600 with 8gigs mem and 2gforce gtx 550ti sparkles in sli.
I fixed this going to the main folder of the game and in legends.exe (the client launcher) right click -> properties -> compatibility tab -> check the "Disable display scaling on high DPI settings"
Some old games doesn't support high DPI settings that you change in the resolution window
Hope it works! good luck
