After installing  KB2495644, I went to, instead of reporting that I had installed version 4.0.60129.0, it reports that version 4.0.51231.20 is installed.

If I Launch Internet Explorer 
	Select Tools » Internet Options 
	Click the Programs tab 
	Click the Manage Add-ons button 
	Select the All Add-ons option
	Look for Microsoft Silverlight and note the version number - it shows 4.0.60129.0

I am having almost the exact same problem in that the same two versions of Silverlight are involved. I uninstalled and reinstalled Silverlight in an effort to fix a problem with an out-of-browser (OOB) Silverlight application that was always giving a "Catastrophic error" message. I uninstalled the OOB app, uninstalled Silverlight, reinstalled Silverlight and after that the message I get from is:

An earlier version of Silverlight has been detected.
Installed version: 4.0.51231.20
Current version: Silverlight 4 (4.0.60129.0)
You may need to restart your browser.

Like dcassidy, I also find that IE's add-ons manager tells me I already have the newer version.

I have restarted the browser and rebooted but that doesn't change anything. I am using IE 8.0.7600.16385 (32-bit) and Windows 7 Enterprise (64-bit).

I would appreciate any tips on how to clear this up as it is preventing me from doing my job as a software tester.
