What... precisely... is the error message?
Thank you, Mike! This is the error message after it tried to install:
"Adobe Flash Player 12.0 Installer
Installation failed [white letters in a blue bar]
[red triangle with exclamation point] This installation failed.
Do you, Mike, or anyone else know how to fix this? It is a three-year old iMac, with 16GB of RAM, a ton of space free on the HD, and on which everything (including prior versions of Flash) install and run perfectly. It is running Mavericks. I have NOT yet had a chance to reboot the system. Any idea how to get Flash v. 18.104.22.168 to install?
I tried your suggetsion, but I got an error message again (please see below).
However, I then tried (A) rebooting and (B) installing from a downloaded .DMG, and that combination solved the problem (i.e., Flash installed just fine).
Thank you for your time and efforts. Very much appreciated!
