Aliens vs Predator 2 installation problem

[Locke99]

I tried installing Aliens vs Predator 2 but I got a catastrophic kernel error at 97 %. I tried to uninstall but it would not work so I just deleted the whole "Fox" folder. Now every time I try installing it again a popup menu asks if I want to delete the components. I click yes and it says that it couldn't remove a few files in the windows directory but it won't tell me which folder these files are in. It won't let me install the game anymore. Is there any way to get around this?
