When installing updates using Windows update or Microsoft Update you may

receive Error 0x643 or 0x80070643 (23 Oct-09)

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



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.
