Uninstall the current version, then download the version you want from http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html
Use the Flash Player Settings Manager to disable automatic updates.
Is it possible to get some on-line assistance with this? I am not sure which one I should download and then it asks me where I want to store the player, etc.
You want to download the last 11.7 version, which is 11.7.700.242
The download is a ZIP file, and you will need to extract and run the appropriate installer for your system
Windows: flashplayer_11_7r700_242_win.exe and flashplayer_11_7r700_242_winax.exe
Mac OS: flashplayer_11_7r700_242_mac_intel.dmg
