Have tried several times on my own -- and with Apple Tech support to get the Adobe Flash Player on my I Mac to finish installing. I got it to initialize, but to finish the process, it only goes part way (36% or 28% or 26%) and then locks up and won't go complete the process. Safari is not on. Was on tech support call for 2 1/2 hours and we tried different browsers and methods -- still had lock up problem. How can this get fixed?
