I have failed several times to install the latest Flash Player 12. I am using Safari. Is that the problem in and of itself??? I followed the help suggestions for installing on a Mac. I successfully uninstalled the previous Flash Player. The dmg download works but when the window opens with the install folder to dbl click, I notice the layout is messed up: icons overlapping and such. The installer launches and goes through the initial screens. At the end when I expect it to say complete. It shows a check but says "unable to proceed with the installation". I have also tried changing the update preferences to see if that made a difference. Nope.
If anyone has an idea of how to solve this problem, I would appreciate your advice. Thank you.
