I really can't tell you how many times I have installed/uninstalled/reinstalled Flash Player.
Download stalls at 7%, then download times out suddenly (no progress) at 47%.
Installation fails in Firefox 20 and Safari 6.0.4. under Mac OS 10.7.5.
While I was typing this, I tried to install one last time. These are the steps that appeared to work for me.
1. did NOT double-click 'Install Adobe Flash Player.app' this time
2. followed directions found on Adobe webpage, right-clicked Contents>Resources
3. double-clicked 'Adobe Flash Player.pkg'
*This* time, I got to the Installation Successful screen.
However, the Download webpage Version window is blank. So I can't really tell if AF is installed.
I downloaded again and got into the same failure loop. Help....
