error installing dell support center 3.0

I downloaded the installer from dell for support center 3.0, but when i click to install it I get this error message. (object reference not set to an instance of an object). I'm running xp pro on a dell xps gaming system630i. I was told i needed to download the full 49 meg version of support center 3.0 and not the installer dell is giving me. Any one know where I can download it. Thanks
