Can't uninstall a previous iTunes installation

I am "new" to Windows, had 6 years on a Mac, and before that I worked on 95... so forgive the total ignorance. Most of the advice is way above my head, but I did look up the Windows Installer CleanUp Utility. I tried to download it, and it would not load properly. I get the following error:

Script:
C:\Users\XOPHER~1\AppData\Local\Temp\IXP000.TMP\StartMsi.vbs
Line: 17
Char: 1
Error: Permission denied
Code: 800A0046
Source: Microsoft VBScript runtime error

Any suggestions? Thank you.

If anyone still looks at this thread i would be very appreciative :)

hi everyone,
i have installed the windows installer cleanup, but cant find it on my computer other then the downloaded msicuu2.exe file. so from here how do i uninstall itunes and would this cause me to loose any data sorted in itunes if i was to install the newer version of itunes later on?
