how can i force install a vista .msu update?

[NuVanDibe]

i'm getting the video card black screen on startup error, where the pc becomes unresponsive just before the login screen. there is a fix for this, KB938194, but when i try running it, it says "The update does not apply to your system"

i know for a fact that it is meant to fix the exact problem i'm having. i'm willing to risk ruining my installation. just someone please tell me how to install this thing manually...

edit:

p.s. i am using the proper version of the update for my version of vista. please don't reply with anything like, "you should download the update for your version of vista." or "are you sure you're using the x64 update with x64 vista?"

The only reasons I can think for this error would be either if you were attempting to install the x64 package on x86 or x86 package on an x64 box, or if you're already running the SP1 beta.
