I would appear that the tutorials on our Screencast.com site require people to have an Adobe Flash Player 9 installed (the flash player is pretty standard on most computers, it is the upgrade that is new.) The upgrade is available for free from Adobe.
One person wrote in and asked if the correct viewer is the Adobe Flash Player or the Adobe Shockwave Player. Duncan Dixon helped me with this one and told me that the correct player is the Adobe Flash Player.
Both are available for free from the Adobe site, and may already be installed on your computer if you allow your computer to install upgrades. If not, go to:
It will tell you if it is already installed or not. If not, it has a link to their download site, and from it select the Flash Player.
