Window Installer Error

[Guest]

I was using itunes and it asked if I wanted to update which I clicked yes.
Started updating then an error appeared:

"Error 1920, Service Bonjour Service"...

followed by

"Error 1603 fatal error during windows installer, help (Msi.chm) or MSDN for
more info"

I installed Window XP Pro after iTunes. How can I resolve this problem?

Thanks

Uninstall and reinstall iTunes.
