Hi all,
This is likely an issue with the Silverlight 2.0 install process, which is also in beta form. I'm guessing that most of you have previously installed the Silverlight 1.1 Alpha. I HIGHLY recommend removing that first before installing Silverlight 2.0.
Also, we've found that a browser restart helps some operating systems (e.g. Windows XP), even though the installer only asks for a page refresh.
Please let us know if you continue to have issues. Thanks!
