Hello all,
I am running Windows 7 Professional x64 and am unable to install KB2804576 (Security Update for Microsoft .NET Framework 4 on XP, Server 2003, Vista, Windows 7, Server 2008, Server 2008 R2 for x64). I have tried installing it by using Windows Update and manually downloading the NDP40-KB2804576-x64.exe file.
When I attempt to install it through Windows Update, I get a Code 656 Windows Update encountered an unknown error message.
When I attempted to install it using the NDP40-KB2804576-x64.exe file, I was getting a The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for
assistance. error message. Then, after I ran the Automatically diagnose and fix common problems with Windows UpdateMicrosoft Fix it program, that error message was replaced by a

- Using Task Manager to close explorer.exe and then start explorer.exe again
- Right clicking on the NDP40-KB2804576-x64.exe file, and clicking Run as administrator.
