I tried downloading Adobe Flash Player 10 for YouTube, but YouTube is still not working. What can I do?
You can check minimum system requirement for runnning it at http://www.adobe.com/products/flashplayer and can download the appropriate prog. Adobe also provides online testing for Flash Player at http://www.adobe.com/shockwave/welcome/ (This page will also tell you which version is currently installed in your machine (if it is installed) and provides a list of the latest player versions for each platform)
Firstly, I suggest you download and install Adobe Flash Player version 184.108.40.206. Once you install it, follow the steps provided by Adobe Systems Incorporated and enable the plugin. They are providing instructions for Opera, Chrome, Mozilla Firefox and Internet Explorer.
