OBIEE 11g - Flash Player 10.1 required

To display graphs as Flash objects in your browser, you need to have Adobe Flash version 10.1 running.
If you do not have this version, what you will see when you open up a Dashboard page or Analysis containing graphs will be something like this:

So, you need to upgrade to Flash Player version 10.1 or install it if you don't have any version of the Flash Player installed.
