I got a computer that had Silverlight 1 already installed on the computer. My work schedules require Silverlight for their website but it needs Silverlight 5. I download the new version, try to install it and it says "Message ID: 1603"
and doesn't help at all. I have uninstalled it. I have completely uninstalled, rebooted, etc. But, when I download Silverlight 5 again, it shows up as Silverlight 1.
