I have Googled and searched this community for an answer for 9 months, and I have found nothing.
I need to update Flash Player on my Mac Pro 2 x 2.66 GHz 6-Core Intel Xeon with 8 GB 1066 MH DDR3 RAM. I'm running OS X version 10.9.3. I am able to download the update, but when I try to open it, I get this:
This continues to happen, even with each further update I attempt. FYI, Flash Player works just fine in my browser (Firefox), but at some point, my Flash Player is going to be so outdated that it won't work. I have no idea how to handle this problem. Any help would be GREATLY appreciated.
