Why can i install Security Update for Microsoft .NET Framework 4?

I try to install "Security Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008 x86 (KB2446708)" using windows Automatic update service, in many times, but i can't. Always show "66A error". Windows update center only show error for this "Microsoft .NET Framework 4 " update. (Other updates successfully install.) Then i manually downloaded its .exe installer and try to install it. Then i receive this error. How do i install this security update?

Try this:

Error code 66a .net framework 4 - Microsoft Answers

Quote:
A. Click on Start and click on Control panel.
B. Go to Program and Features.
C. Scroll down to Microsoft.Net Framework 4 Client Profile, right click it.
D. It will give you a choice of Uninstall/Change, click it.
E. Then, it will give a choice to Repair it, pick Repair it. It will take about 4-10 minutes to repair (with my PC) your experience may vary.
F. When completed, go to your update center, and update it again.
