Finale 2010, from the CD ROM. The CD opens up, but in the window where you click Install to install, nothing happens. It goes no further. Finale support says this:
Question
Why am I unable to click the Install button in the Finale installer?
Answer
During the Finale installation wizard, if you are unable to click the Install button, the Installer.app application may have become corrupted or damaged. To solve this issue, please re-install the Installer.app application from your OS X disk or contact Apple Support for more information.
I have no idea how to reinstll Installer.app from my OSX disk that came with the iBook. Also I Googled installer.app and found a download link from Cnet (developed by RipDev), but it seems to be no longer there, and I get taken to a strange netherworld when I clicked on the link.
