Installing Flash Player, any version

I've tried installing Flash Player 13 on my iMac. I'm running OS X 10.9.2. I've tried the installation on both Safari and Firefox. I've read the notice that Adobe is working on the problem and followed the suggestion that I uninstall Flash Player and then install version 12. The problem is once uninstalling was successful when I tried to install version 12 I kept getting a window saying the page that the link is supposed to take me to couldn't be found. Now I have no version of Flash Player and can't view anything requiring this plugin on the web. Can anyone please give me a way around this problem? Thanks for your help.
