I was doing the rounds and updating 2 machines, running XP Pro and 2003 Server, with Silverlight 3 run time pre installed on them. When the update was complete I couldn’t view any Silverlight based web sites with IE 8 on both machines.
I would only receive an install Silverlight message. It was as if Silverlight was not installed on the machines any more.
A quick check in the IE installed component list (Tools/Internet Options/Programs/Manage add-ons/Show all add-ons) showed me I was automatically upgraded to Silverlight 4 (Version 4.0.50524.0) which seems fine.
To solve the problem I did the following:
1. Went to http://www.microsoft.com/silverlight/.
2. Pressed the install Silverlight button which crashed the installer (on npctrl.dll).
3. Restarted the browser at which point I got a message telling me I need to restart the browser again.
4. Restarted the browser for the second time which made Silverlight runtime and IE happy and willing to play together again.
