Great job getting Flash Player 9 out the door, after absorbing Macromedia. Pity it doesn’t install correctly on a Mac.
I ran the installer, and it launched Safari when it finished, taking me to your “gee, isn’t Flash cool?” page. Which didn’t load, because I didn’t have Flash. So I ran the installer again. And again. Still no Flash.
So I deleted the old copy from /Library/Internet Plug-Ins, and ran the installer again. It failed, because it didn’t have permission to write to that directory. Yes, it’s true; when you want to create files that require administrative privileges, your installer actually has to request administrative privileges. It can’t just hope that the user is logged in as root, or has foolishly made that directory world-writable.
