Mac OS. I cannot update or Install Flash player.

Question

I cannot update (or install) Flash player. Using FireFox (Latest version as of this morning.) Mac OS 10.11.5 on a Mac Pro Tower.

I DID have version 21, version 22 is the latest. I get.

"Adobe Flash Player could not be installed."

I have done the troubleshooting steps below. Everything is good as far as I can tell.

My Shockwave Flash WAS set to, "Always Active".

I ran the Adobe Flash Un-Installer which did succeed. I then attempted a new installation, still no joy. ( It did remove Flash Player version 21, now I have nothing. )

I've done several Mac restarts and re-tried the installation. Flash will not install.

Suggestions appreciated.

I am having this same problem and tried the solution. It didn't work. I have embedded flash in Chrome, and it is enabled, but it's running 18.0.0.209. I disabled and re-enabled it to no avail. How can I get my flash to update?
