Automating mouse clicks and key presses seems backward and stupid. Doing this manually will also get disrupted. You should trace the executable and analyze the function calls. Get a million samples then form a statistical model. The production model replays the function calls given some input. Doesn't need graphical memory anymore and it also has higher resolution inputs (function symbols, addresses) than coordinates on a screen.
