Adobe reader and flash won't finish installing

Every time I try to play a youtube video, it says to update the flash player, so I go to update it, it downloads the update, and when I hit run, nothing happens. I hit it again 2 minutes later, it says "only one instance of this can run". Win 7 x64

Your system details list doesn't show that the Shockwave Flash plugin is installed and enabled.

  • Firefox/Tools > Add-ons > Plugins

You can find links to the latest Shockwave Flash player for Firefox on this page:

You can verify on the Adobe Flash Players Test Page that the Flash plugin is working and which version you have.
