Photoshop :: Missing Module In CS3 Ext

I downloaded the trial version of Photoshop CS3 Extended, and at first it looked like everything was going well, but when I try to open of create a new file, a pop up opens with saying this:

(header): Adobe Photoshop CS3 Extended: Photoshop.exe- Fatal Application Exit

(message): The specified module could not e found. C:Program Files Common Files Adobe Version Cue CS3Client3.1.VersionCue.DLL

After this message appears I can click Ok or Cancel, but both just close the whole program.

I have no idea what it means or what I should do, but I uninstalled the program and the install package and re-downloaded the install package and reinstalled the Program, and the message still appears.

I know that I'm using just the trial, but how do I know if I want the program if it doesn't work.

I'm Running on Vista.
