Vista - Aegia Physx wont install!!?

Aegia Physx wont install, help i just got new graphics card (9800GT XFX 512mb overclocked) and when i installed physx it just comes up with, "installation ended prematurely because of an error" WTF IS THAT, HELP ME, how can i remove all traces and get it to work!! PLZ HELP
And there are a few work arounds but im a newbie (as it says below my profile name) so u need to explain it step by step plz @(

Did you install from administrator or a user account? Did you use the 64-bit drivers?

Have you actually got an Ageia Physx card? Or do you want the Nvidia Physx?

Graphic Cards - GeForce® 9 Series - Nvidia GeForce 9800 GT

Its the 512mb xxx edition i cant remember if its an actual physx card but it definitly can support it!!

I am administrator i created it via cmd

Aren't those drivers for the actual Physics card. Your Physics support is most likely part of the drivers and hardware already.
