Microsoft has announced in a
Press Release that Silverlight 3 and Expression 3 are now available. You can go to the
Silverlight home page and download the newest version.I did this today and successfully downloaded and started the install of the new version:

Unfortunately, I soon hit a wall:

(link on dialog vanished when I did the screen capture)
Thankfully, I was given the link for more information in the dialog so that I could figure out the issue. As you can see, the help was.....:

Okay, so there was no more help. I could dig and find the answer to my issue, but I have to step back and ponder for a moment. I've had Flash upgrade on my machine through a variety of versions. I don't recall running into any issues that stopped the install. I'm this install of Silverlight 3 is an exception isolated to me, then no biggie for anyone but me. If it isn't isolated to me, then I think Silverlight is going to lose a few more point to Flash....
Did Silverlight 3 install for you without issue?
Hi Brad -
Thanks for reporting this. This was a known (temporary) glitch on the website on Friday, but we've gotten it straightened out since then - everything should be running smoothly now.
thanks!

Thanks for the update Tom! I'm sure I wasn't the only one with the issue, so knowing there is a solution is good.
It is worth noting that the standard Silverlight 3 does not initially install, but that the help for the error (if you click on the link in the error dialog) does take you to a page with another link that lets you update Silverlight for Developers. That update then works.
Not the smoothest path to updating, but it does work in the end.
