When clicking on certain screens in the Controller, you may encounter the message "Please install Flash to use this feature." This is due to the fact that a few screens in the Controller UI leverage Flash and require Flash Player 10 or greater. AppDynamics recommends version 11.
This behavior is specific to Chrome and you must explicitly enable Flash. While we are moving away from Flash to HTLM5, there is no ETA on when Flash will be completely removed.
To resolve this, click on lock icon to the left of the address bar. Under the Flash select, click "always allow on this site." You will be prompted to reload the page, after which you should no longer see this message.
Alternatively, go to chrome://settings/content/flash and add the controller URL as an "allowed" site.
