To see what it would do I installed the KB917422 update of windows XP, and now it doesn't give me the error again,
but it doesn't launch the game at all, nothing happens, so I'm gonna uninstall that update again.
Does someone have another idea? Do you maybe need windows xp home edition instead of pro?
And why is my game in English when I install it on my laptop, and is it not in French?

Strange, isn't it. My game is only in French, so that's really odd.
But it doesn't work on my laptop either, so.
