I had this same problem and Microsoft sent me this e-mail on how to fix the
problem. It worked great! The only thing that I had to do different from what
she had said was I couldn't find the "netfx.msi" file and just ended up
clicking on the .NET Versin 2.0 application file to install .NET 2.0. Once
you do all of this and then reboot the Microsoft update shield disapperead.
That should take care of all of your update problems associated with
KB886903. Best of luck!


Thank you for contacting Microsoft Windows Update Support. My name is Cary
and I am glad to work with you.

From the case log, I understand that Security Update for Microsoft .NET
Framework, Version 1.1 Service Pack 1 (KB886903) failed to install and we
couldn't remove it. Please be assured that I will try my best to help you.
However, if I have misunderstood your concern, please feel free to correct
me.


This error code can be caused by damaged temp files.

First, let's use any of following methods to remove the previous version of
..NET Framework:

Method 1: Remove it from Add/Remove Programs:

1. Open "Control Panel" and start "Add/Remove Programs".
2. Remove all versions of .NET Framework from the programs list.

Method 2: Use the .NET Framework Cleanup utility

1. Please download the Cleanup tool from the link below and unzip it to the
desktop and you will get a file Cleanup_tool.exe

After removing previous .NET Framework installation, please download the

Package (x86) from the following link and save it to the C drive (C:\)

2. Click "Start"->"Run", type "C:\dotnetfx.exe /t:c:\Framework /C" (without
quotation marks and there is a space before "/C") in the open box and click
"OK".

Note1: If you are using Windows XP SP2, there may be a Security Warning box
to prompt you for clicking "Run" to execute the command. Please click it.

Note2: If you are prompted to create this folder, please click Yes to
continue.

3. Locate the folder "C:\Framework" and double click the "netfx.msi" file to
install .NET Framework components.
