Silverlight update KB982926 failure and solution

by APIJunkie 4. June 2010 23:29

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.

I was first wounded by x86 assembly, recovered and moved on to C. Following a long addiction to C++ and a short stint at rehab I decided to switch to a healthier addiction so I am now happily sniffing .NET and getting hooked on Silverlight.

I am mainly here to ramble about coding, various API’s, Junkies(me especially) and everything else that happens between coders and their significant other.
