Reminiscent of the early days of the internet where companies built their websites that would only work on Microsoft browsers. Locate the 'Install Silverlight' area in the lower-right part of the window. If you are running an Intel processor, click Mac Runtime next to 'Silverlight 3.' Otherwise, click Runtime for Mac PowerPC next to 'Silverlight 1.0.' After the download is completed, installation should start automatically.
