Mac OS X 10.4: Unable to install iPhoto or iMovie from iLife ‘05 disc

In Mac OS X 10.4, you will not be able to install iPhoto or iMovie directly from their respective "package" files on the iLife '05 disc. You may see the following:

• Volumes are dimmed during the installation process.
• Moving the mouse over the dimmed volumes displays the message, "A newer package is already installed," even though you haven't installed iPhoto or iMovie yet.

Instead of trying to install these applications from their individual packages, use the iLife Installer on the iLife '05 disc. You can then use the "Customize" option and select only the applications that you want to install.

This should not occur in iLife '06.
