1. In the Control Panel, open the Add/Remove Programs applet (Programs on Vista) and uninstall Microsoft Silverlight if it is shown as installed by clicking on it and then clicking Uninstall or Remove. If you get an error on this step (for example a dialog saying that the .msi file cannot be found), just continue on to the next step Note :Be careful that you only delete what I say to delete below. If you delete too much by accident it is quite likely that you will break something and there is no way to undo accidental changes 2. ClickStart, and then click on Run. Ø Typeregedit in the Run box and click on OK. Ø In Registry Editor expandMy Computer and then expand HKEY_CLASSES_ROOT and navigate to INSATLLER Ø ExpandINSTALLER, and then expand PRODUCTS Ø UnderPRODUCTS right-click{D7314F9862C648A4DB8BE2A5B47BE100**} andthen clickDelete** **** 3. Try updating or installing Silverlighthttp://www.microsoft.com/getsilverlight , if this step failsjust continue on to the next step 4. Using regedit, navigate to HKLM\Software\Microsoft\Silverlight and delete the key 5. From an administrator command shell you can do this by running: reg delete HKLM\Software\Microsoft\Silverlight /f 6. Using Windows Explorer, delete the “Microsoft Silverlight” directory from under Program Files.

From an administrator command shell on anx86 you can do this by running: rmdir /s /q "%ProgramFiles%\Microsoft Silverlight

If you are on a64-bit version of Windows, substitute ProgramFiles(x86): rmdir /s /q "%ProgramFiles(x86)%\Microsoft Silverlight 7. Try updating or installing Silverlighthttp://www.microsoft.com/getsilverlight 8. If the issue is related to playing Media Streaming using third party players from any website then try resetting the Internet Explorer to defaults
