In the Flash Player 20 admin install guide under "App Installer for Macintosh" the directions for silent install are as follows"
"Run the installer contained in the .app file using the following command:"
sudo ./Install Adobe Flash Player.app/Contents/MacOS/Adobe Flash Player Install Manager -
The only problem is that there is no "Adobe Flash Player Install Manager" in the "/Install Adobe Flash Player.app/Contents/MacOS/" directory. Therefore the install fails.
Did Adobe forget to put the Install Manager in the FlashRemote20 package?
