Software Deployment

I need to deploy iTunes via SCCM with preconfigured user settings and disable self healing. The problem I'm having is with the last part, no matter what I try I cannot find a way to prevent the self heal from occurring on the first launch for each new user. I've disabled all advertised shortcuts, checked for active setup entries, imported all files and registry keys changed as part of the repair, but still every time it runs when you launch iTunes (even straight from the executable). Could anyone give me any pointers in tracking down the entry point for the repair? This didn't use to happen with the previous version we configured like this (11.0), what's changed? Many thanks, Matt
