When I attempt to install Leopard on my old 17" PowerBook I receive a strange error message:


Install Failed

Mac OS X could not be installed on your computer

The installer could not validate the contents of the "address book " package.

Contact the software manufacturer for assistance


Then I have the option to Click Restart to try again, and the same message reappears


Thanks in advance for any assistance



PowerBook, Mac OS X (10.4.7)
