Flash Player quit working. Flash Player 11 does not install. Have osx 10.7.5.

Adobe Flash Player installer indicates that it has installed Flash Player 11 but it does not show up anywhere on computer and things which require Flash Player will not run.

Download the offline installer here: http://fpdownload.macromedia.com/get/flashplayer/current/licensing/mac/install_flash_player_11_osx.d...

If it won't download directly, right click and "Save as"

Go to: Mac HD/Library/Internet Plugins

Trash the Flash Player.plugin file from there

Go to: Mac HD/Library/Application Support/Adobe

Trash the Flash Player folder (the whole folder)

Empty the trash

Reboot

Mount the DMG and run the installer.

BEFORE opening any Flash content in Safari, Go to: Safari>Preferences, and check the Security tab to make sure "Allow all other plugins" is checked.
