AdobeFlashPlayerInstaller_11_aih.dmg is a very old installer file that is no longer in use. If you downloaded this recently, please provide the URL that you downloaded it from. Please go to https://get.adobe.com/flashplayer to download the latest, valid/usable, installer.
Hi Maria! Thanks for the timely response.
Utilizing the link that you provided, I downloaded AdobeFlashPlayer_23_a_install.dmg and the installation worked perfectly. Apparently I was inadvertently invoking an older version of the installer that I found in my Downloads folder.
Well done and thanks again!
You're welcome. The installers change constantly, so it's always a good idea to download the latest version, instead of using an old one.
