Hello, you either have JavaScript turned off or an old version of Adobe’s Flash Player. Get the latest Flash player.
Since Javascript was enabled, in order to check whether this was a problem of Youtube’s site only, I browse to other sites that I know use flash tech to find that I was really unable to watch any Flash content. They all prompted me to download and install the latest version of Adobe Flash Player.
So I visited Adobe’s site and tried to get the latest Flash Player online. The key thing is that after installing the add-on, the movie clip that always appear on the site saying that your installation was successful didn’t appear at all. Strangely, by refreshing the page -by hitting the F5 key- it did appear. Weird.
So I said, maybe this was just a minor glitch, and opened the video page on Youtube. Unluckily, that nasty message appeared again.
This time, I opened the “Tools” menu of IE8, and selected the “Manage Add-Ons” section. There, I found that the “Shockwave Flash Object” add-on was in fact installed and the version was correct, so I tried to “reset” it by disabling the component, closing the browser, re-open it and finally enable the add-on. No luck!
One final desperate move: just in case, I just opened the following menu on my browser:
“Tools -> Internet Options -> General -> Delete”
and deleted everything. Then, I downloaded the offline installer of Adobe Flash Player from the following link:
http://www.adobe.com/support/flashplayer/ts/documents/tn_19166/Install_Flash_Player_10_ActiveX.zip
And finally, I closed the browser and executed the installer (btw, since the offline installer does the task of uninstalling any previous version of the add-on, I skipped that part and let it do it for me).
When the process ended, I just reopened IE8, visited Youtube again to find this time that everything simply worked just fine!
I don’t know if this workaround will work for you, but if you happen to experience a similar situation then just give it a try.
Well, that’s it for today. I hope you find this post useful.
