Question : Problem: ITunes upgrade results in the application crash

Hi,
Machine OS - XP sp2
I have a user that upgraded their ITunes to the latest version - I apologize that I don't have the version number in advance because I'm not directly involved.  The problem is once the update was installed they go to open iTunes and it opens and a few seconds later the application shuts down.  There was no error message with a code or anything.  It's a generic message that says 'ITunes encountered a serious error' Sorry for the inconvience.  

The tech tried the usual un-install and re-install and the problem persists.  Does anyone know of away to completely remove Itunes from Win XP including registry Keys and other places it leaves it's information.  So I could do a fresh install, I really don't want to have redo this persons machine because of iTune.....it doesn't help that it's the boss's daughter.  Any help would be appreciated.

Thanks!
