Cannot install Flash Player 21 on Mac OS 10.11.4 El Capitan. Safari Version 9.1 (11601.5.17.1). Have tried multiple times. The "Disk" downloads, I can double-click on the image, and it shows the Install folder, and I can double click on the enclosed image, and that's where the process stops. Having checked the Forum, it sounds like MANY other Mac El Capitan users are experiencing the same problem. Please help! Quickly!!

    try installing after a restart with no other programs open. that worked for me.

    you may have to try a "safe" restart.  --- hold shift key down when restarting.
