Vista - VBScript Runtime Error 800A0046 Dell 944 Printer Software/Driver

In trying to install Dell 944 printing drivers/software (64XPPro) onto Vista
64, and after downloading through Dell's website off IE7, then unzupping
files, this Vista error box VBScript runtime error; code 800A0046; Permission
denied; Script: C:\drivers\printer\944\dlcdEN.vbs; Line: 11; Char: 1 . . .
all comes up in the Vista pop up dialog box. The printer is brand new, is on
a dell wireless adapter 3300, all installed and working correctly, but for
this software/driver 64bit package which I just got from Dell website
download, because the printer originally came with a 32bit driver/software CD
that wouldn't work at all (because of the 64bit I'm assuming).
This seems like a minor issue or privacy/security matter that could be
easily fixed, at least i'm hoping. Can anyone help me in this regard or might
be experiencing the same thing?
Thank You
