I have tried repeatedly to uninstall existing Flash Player and install Flash Player 11 (188.8.131.52) on a Mac OSX 10.6.8 64-bit system running Safari (64-bit), without success.
The dialog box says that installation was successful, and if you check Apple / System Preferences / Flash Player / Advanced / Updates, it indicates that "Plug-in version 184.108.40.206 is installed.",
but if I try to run anything requiring Flash, it does not work, and when I go to
under Flash Player Help / Find Version / Flash Player
I see a blank gray box, indicating that Flash Player is not installed.
I have followed all of the instructions on Flash Player Help / Installation Problems / Mac OS and uninstalled and reinstalled flash multiple time, with firewalls and antivirus system disabled and everything active force quit, and I get exactly the same results ... Flash appears to be installed, but does not work ... any suggestions?
Could you please check the following?
Go to Safari Settings > Preference.
Go to the Security tab.
Thank-you. The problem was apparently that enable plug-ins was not checked. Flash works fine now.
