Question

1. Security Update for Microsoft .NET Framework 4 on Windows XP, Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008, Windows Server 2008 R2 for x64-based Systems
2. (KB2478663).

6. (KC2533523).

I'm currently using a window 7 64 bit operating system lenovo laptop and I've been trying to install a update:  However, upon many tries of installing the update, i still couldn't get it install. The error details for the update is Code 66A.

Therefore, after searching on Windows forum for solution for that error, i've tried to repair the Microsoft .Net Framework 4 Client Profile by following these steps:

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.

After following the above steps, the repair did not succeed because: Generic trust failure.

                 I am just plain stuck.
