Then proceed per the following:

~~~~~~~~~~~~~~~~~~~~~~~~

Step #1 => Before doing anything else, write down what .NET Framework

versions are currently installed:

How to determine which versions of the .NET Framework are installed and

whether service packs have been applied

http://support.microsoft.com/kb/318785

Step #2 => Now see Resolution Method 2 in this related KB article:

http://support.microsoft.com/kb/923100

After running the .NET Framework Cleanup Tool (not the Windows Installer

Cleanup utility!), reinstall all .NET Framework versions (but only the ones

you wrote down in #1 above) manually using the download links on the page

then run Windows Update manually to install security updates for same.

NB: If you remove .NET Framework 3.5 (SP1) using the tool, reinstalling .NET

Framework 3.5 will also install .Net Framework 2.0 SP2 and 3.0 SP2 then

Windows Update will offer .NET Framework 3.5 SP1.

IMPORTANT! => If you remove .NET Framework 3.5 (SP1), reinstall your .NET

Framework versions in the following order:

1. .Net Framework 3.5, then...

2. .Net Framework 1.1, then...

3. .Net Framework 1.1 SP1

NB: KB923100 references this page:

http://blogs.msdn.com/astebner/archive/2006/05/30/611355.aspx. Please read

ALL of it as well as the related page

http://blogs.msdn.com/astebner/pages/8904493.aspx before using the .NET

Framework Cleanup Tool.

Step #3 => Check-in at Windows Update and install any critical security

updates offered.
