Once downloaded if it doesn't unzip automatically the double click on that file. Including this and it didn't work for me: I have tried everything to get my Flash Player back-up and running, with no progress. Adobe, as you all know, no longer supports the system. I now keep getting notices that I have an 'unsupported operating system.' I have a Mac OS X 10.4.11 Power PC G5. Here it goes, I cannot utilize my Flash Player anymore - you all know what a pain that is. Pleaseeeeeee Please please, could you help? Okay, first before anyone says anything, I've already read the other discussions on this subject and none of them have helped.
