Unable to run iTunes based VBS files

[Enverex]

I'm guessing this is something to do with Vista because it works fine on my laptop, but basically I'm trying to run a VBS script which clears out duplicates from iTunes. The VBS file runs fine on my laptop which is running XP, but doesn't run on my desktop running Vista x64 Ultimate (only doing so because it exceeds the max spec for XP Pro).

When I try and run the script I get the following:

C:\Users\Enverex\Desktop>cscript Remove_Dup_iTunes_Tracks.vbs
Microsoft (R) Windows Script Host Version 5.7
Copyright (C) Microsoft Corporation. All rights reserved.

C:\Users\Enverex\Desktop\Remove_Dup_iTunes_Tracks.vbs(32, 1) Microsoft VBScript
runtime error: ActiveX component can't create object: 'iTunes.Application'

I've tried reinstalling iTunes and I've tried installing the x86 version of iTunes, no change. It does this for any iTunes VBS script, not just this one (and as I said they work fine on my laptop). Tried using iTunes 7 instead which also had no effect. The "register the vbs dll file" also has no effect (also that's only a fix for the issue of iTunes not installing in the first place).

So any ideas? I really need to be able to sort this out because I can't sync my iPod till It's done :/

Run it as Admin?

User has the highest permissions available and the "run as admin" option isn't even available. Running a "cmd" window results in "Administrator:" being written on the top of the window bar itself (user has access to do anything/everything else).
