update "Successful" now Flash Player has vanished

This morning (11-13-14), upon booting my computer, I received an ordinary update request from Adobe FlashPlayer. I get these pretty frequently. Normally, they update quickly and work just fine. So I clicked Update. Update completed successfully. However, now my Flash Player is completely gone.

So I followed the manual install instructions. Downloaded

install_flashplayer15x32_mssd_aaa_aih.exe

I doubleclicked the file as instructed, and it installed successfully, according to the on-screen messages.  However, when I try to do anything that requires Flash Player, Firefox still claims that there is no Flash Player installed.

One of the troubleshooting instructions on the Adobe Flash Player website said to download the uninstaller for Flash Player and then reinstall. I did that. Exact same result. Flash Player is not installed and does not exist. No error messages. Everything claims to be successful, but the player just doesn't seem to exist.

Next attempt: Downloaded the full 17.0 MB file (install_flash_player.exe), download completes successfully. Install Successful. Same result. --- no Flash Player.

I attempted the install instructions again trying a couple different things including 1) shutting down all other programs during the install process and 2) rebooting the computer after the install process. None of these additional instructions helped. Same result. No Flash Player.

I use Firefox for everything. So I tried IE just for fun. Oddly, Flash Player in IE works fine. *sigh* Flash Player for Firefox still does not.

Any suggestion are appreciated.

System:

OS: Windows 7 Pro SP1

Browser: Firefox 33.1
