First I have to ask if you have installed Flash player at http://www.adobe.com/shockwave/download/鈥?/a>





If yes then the reason can be the following; if you have installed the player with Internet Explorer then it's for Internet explorer and only Internet Explorer shows Flash content, so you have to install Flash Player for any browser clicking on the link that I gave at the top in that Browser. I mean for Opera you open Opera and click http://www.adobe.com/shockwave/download/鈥?/a> in opera.





If you mean that you have a Flash file with .swf extension and you want to open it then you need a Flash Standalone Player installed on your pc (if you install Adobe Flash then the player is included in the install-pack).I just download the latest macromedia and install it but why it don't work on youtube?
Download the Flash Player Uninstaller here:

Shut down your browser, then run the Flash Uninstaller. Go to Add/Remove programs and uninstall Java.


Reboot, then go to www.java.com to install the latest Java runtime and www.adobe.com to install the latest flash player.


Reboot, If you still keep getting the message, go to Control Panel %26gt; Internet Options, Advanced tab, and click on ';Restore advanced defaults';, then restart your browser.
