=> OPTION A: For home users, no-charge support is available by calling
1-866-PCSAFETY (1-866-727-2338; and/or 1-866-234-6020 and/or 1-800-936-5700)
in the United States and in Canada or by contacting your local Microsoft
subsidiary. There is no-charge for support calls that are associated with
security updates. When you call, clearly state that your problem is related
to a Security Update and cite the update's KB number (e.g., KB979906).
Or you can...

Customers who experience issues installing Microsoft security updates also
can visit the following page for assistance:
https://consumersecuritysupport.microsoft.com/
=> OPTION B: First run the Fix It in this KB article & see if the update
will install after doing so:
How to fix MSI software update registration corruption issues
http://support.microsoft.com/kb/971187
If no joy, see...
When installing updates using Windows update or Microsoft Update you may
receive Error 0x643 or 0x80070643
http://support.microsoft.com/kb/976982
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
[As of this post, KB318785 hasn't been revised since November 2008 so you
may not find the pertinent information in it. YMMV]
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.
Download links for .NET Framework Cleanup Tool:

•

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.
