Use the uninstaller
then download, extract, and install 11.6 from http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html
I tried the directions indicated and got a modal popup window with the following message.
Do you have any suggestions how to get around this? I am trying to burn a Smilebox Slideshow DVD
for a Funeral Viewing this Thursday, April 18, 2013. I am unable to do that until this gets fixed.
Thanks in advance for your support.
That should have worked; see this topic for a more detailed description http://forums.adobe.com/thread/1022066
If I saw this message I would try to disconnect from the Internet during the install process.
