I have made several unsuccessful attempts to download Flash on my Mac. I quit Safari as part of the installation process; however, every time I try to use the application I receive the following message:
Adobe Flash plug-in is disabled or you have an old version installed. To start this assessment you need Flash plug-in 9 (or above).
I branched your post to a new discussion topic. The topic you posted to is 2 yrs old and the current version of Safari doesn't treat Flash Player the way it did 2 years ago.
Apple disables Flash Player by default on Safari, like most other modern browsers, and force the user to enable it. Usually on a per-site basis. Please see Enable Adobe Flash Player for Safari for assistance.
