Yes I've tried several methods obtained by google.
The problem is when uninstalling it it needs the original installation file bonjour.msi and in my case that file seems to have become corruted and keeps coming up as an invalid file. I've even tried installing a later version of bonjour and even that wants a valid old installation package.
It's beginning to look a lot like format c: and reload everything unless someone cares to volunteer to tell my wife she can no longer have iTunes.
Even apple says that you have to remove in the following order
iTunes
Quicktime
Apple Software Update
Apple Mobile device Support
Bonjour
Apple Application Support.
THEN you should be able to reinstall iFeckingTunes.
I hate computers.
