Can anyone suggest a resolution? I followed the prompts to download the latest version of iTunes and when completed and rebooted I get the following error when trying to start iTunes; "This copy of iTunes is corrupted or not installed correctly. Please reinstall iTunes" So I download the latest version (9.2.1) from the Apple website and try to unpack the iTunes.mpkg file (128.6mg), it runs all the way through the installation script and then gives me the following; "The Installation Failed The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance." thanks in advance.
