Go to start button and select Control Panel. When the dialog box opens select ';Add/Remove programs'; then select media player and uninstall it. After it's done you may have to re start your computer to complete the uninstall. The just do a search for Windows Media Player 11 and it should lead you to a windows page for installation.
