Safari downloading older version of Silverlight (Getting SL 4 instead of SL 5)

Question

I have a website using Silverlight 5, when an user from Mac wants to visit the site using Safari (because with FF and Chrome it do not work correctly), Safari shows a message: "You need to install Silverlight please click here", when the user clicks on it, Safari starts to download Silverlight 4. This means that the user have to unistall that version and go manualy to http://www.microsoft.com/silverlight/ and download the correct version (Silverlight 5). How can I solve this problem?, because it is happening for all the mac users.
