If you installed iTunes 4.7.1 and try to then install or reinstall iLife '04, you'll get analert indicating that an iLife application is still running even if you have already quit iTunes, GarageBand, iPhoto, iMovie, and iDVD.
This happens because the iLife Installer is seeing a background program called "iTuneshelper," and is mistaking it for iTunes. To workaround the issue, bypass the login items by following these steps:
- From the Apple menu, choose Log Out.
- Log back in and immediately hold the Shift key down. Release the Shift key when you get to the Finder. This will keep iTuneshelper from loading.
- Install iLife '04.
- Restart the computer to allow the login items to load again.
This does not occur with later versions of iLife or iTunes.
