My Adobe flash player is updated but when I try to use it, it says it needs an update

Most browsers at this point are blocking Flash Player by default.  You'll need to activate Flash Player in the browser in addition to having a current version.

You can find instructions on enabling Flash Player here:

It's also the case that malware authors will often times try to impersonate legitimate update notifications in order to trick you into installing malware.

Always download Flash Player directly from Adobe, or better yet, set it to update automatically.

Here's the official download URL: https://get.adobe.com/flashplayer

Please provide a direct link to the content that is not working.

Please show the "needs an update" message. Please bear in mind that there are MANY sites with a virus which put up FAKE update messages to trick you.
