Vista - How can i install WOW on Windows Vista Ultimate

I downloaded the full version at the WOW website and i kept getting this error
The file
"Files\unconditional\user\Data\enUS\Interface\Cinematics\WOW_Intro_1024.avi"
in archive "D:\Installer Tome 4.mpq" could not be opened, because an error
104 occurred. If this problem persists, please contact Blizzard Technical
Support. (MPQFile::OpenFromArchive)

I also turned off UAC but is Windows blocking the program im trying to
download?

1024I'm guessing you downloaded the version from online, and you're
attempting to install the game, but when you get towards the end of the
install, or the 4th CD file (installer tome 4.mpq) your installer is
having a problem with that file and exiting.

First guess is the file you downloaded probably has an error in it. You
may have to download that file again, or run a check to see if the file
is corrupt.

I searched on the Blizzard support website, and found this article that
mentions Error 104:

Apparently sometimes other applications running on your system cause
this error. Read the page above, it has links to troubleshooting
installations. That might help.
