c# Global Mouse/Keyboard Hooks

I know that Global mouse and keyboard hooks are not support in managed .net code. I still need to implement them anyway. I have seen the three different samples on codeproject. I have tried them and they work. Now here comes the BUT: I need a global hook that will work compiled under any CPU. I have not been able to find one that will run on 64 and 32 bit without making several modifications for each OS. I basically need MouseMove, MouseDown, MouseUP, KeyUP, KeyDown global events. I just need it to work on 32, 64 bit os for windows 2000+ products. Thanks and good luck.
