Current version of "Adobe Flash player on your computer has critical security issues" notice in security window

[cb_ward]

Using 21.0.0  Flash, Mac OS 10.22.5, Safari 9.1.1

I have installed the latest version of Adobe Flash 3 times in the last week.  Although it seems to install, it doesn't work.

In checking Safari security I received the above notice, "Adobe Flash player on your computer has critical security issues"

It worked briefly after I installed the new OS 10.22.5 (El Capitain) and the accompanying new version of Flash, but now when I go on a website requiring Flash I get a notice the my version is out of date and the site provides a link to install the latest version.  I do not use the link (maybe its a fake link?) and go to the Adobe website where I download the latest version for Mac.  I have done this 3 times and it still doesn't work. The notice in the security window that there are critical security issues concerns me.  Is this a valid issue with the current Flash software? Can anyone at Adobe address this?
