i've looked at the CD that comes with my controller and noticed that there could be a silent .msi file. but upon trying to executing it, it says i need to run another app found in the root of the CD. as a result i cannot silently install this program to allow the Controller to be on my XP. has anyone tried to install a 360 controller silently?

Maybe you can try to download the latest version from Microsoft and see if you can run it with /? to see the supported command-line paramters.
