Bioshock Demo Install Error

[Software Junkie]

I've just tried to install the Bioshock demo, which I downloaded from Fileplanet yesterday and unlocked at 12:00 (UK).
I'm trying to install it on my Vista 32bit Ultimate OS, but when it gets right to the end I get the following Unhandled Exception error:
"Error Number:0x80040702
Description: Failed to load DLL:GameuxInstallHelper
Setup will now terminate."

The setup then quits and erases the gamefiles from my hardrive.
I thought it was because I installed it on a different drive and not the default location, but either way I still get the same error.....
All drivers and OS is up-to-date. Core 2 Duo E6600, 2Gb RAM, 8800GTX, etc
Help!

Yeah i'm getting the same thing. It still encripted so i can't unzip the file and download it! I have the download manager on and everything but it doesn't seem to want to unlock it. *cries*

Mine is de-crypted, but the problem still exsists. It installed on my XP partition no problem, so I know that the installer isn't corrupt. It's a Vista 32bit problem only for me.
