KB2804577 keeps installing itself

This update has installed itself four times this AM. After it installs, a few minutes later, it wants to install again (automatic updates). In add/remove programs, it shows installed. I have removed it and let automatic updates install it again but same problem.

Perhaps .NET is corrupt?

Check file C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Security.dll

 

In XP version of file must be 2.0.50727.3646. My old file had version 2.0.50727.3644.

 

Replace System.Security.dll with version 2.0.50727.3646 and restart Automatic Updates service.
