flash-player

I have been trying to update my Adobe Flash Player for hours.

I've read the forum, downloaded the uninstaller, restarted on every attempt. Tried for Firefox and IE.

When I click on the downloaded icon, it disappears and this message comes up: "only one instance of this application can run".

Also checked Adobe and other various sites for a solution. I need my browsers, with Flash.

Can someone help?
