Flex 3 and flash plugin error

Question

I have built a flex 3 application using Flex Builder. I am then embedding it in a portal application but having problems with installing the Flash Player

When i load up my application in Firefox or IE6 (without Flash installed) i get a message where my flex app should be,

("Additional plugins are required to display all the media on this page")

When i click to install the plugin i get another error:

(Unknown Plugin(application/octet-stream)).

The plugin does not load and im left hangin. If i then go and manually install the Flash plugin the app works fine however i dont want other users to experience this difficult. Anyone have any suggestions? im using Flex Builder 3 to build the project

Answer 1

Try using SWFObject to embed your flash object into the web page. In the alternative content part (you'll see what I mean, just check the docs), put the following:

<a href="http://www.adobe.com/go/getflashplayer"><img border="0"
src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" 
alt="Get Adobe Flash player" /></a>

SWFObject should also take care of the situtation when there is a flash player installed, but its version is too low for your app.

Answer 2

Does the Flash on this page work, or do you get the same prompt? http://www.adobe.com/products/flashplayer/

If you get the same prompt, don't let the browser install the plugin. Instead use the download link on that page and install Flash player manually, preferably as a user with administrative rights.

Reboot your machine and try again.
