Error Code 0x643

[BillAllen]

I just ran a manual Microsoft Update and all the high priority updates were

successful. However, two "Software, Optional" updates failed. They are the

following:



Microsoft .NET Framework 2.0 Service Pack 2 Update for Windows Server 2003

and Windows XP x86 (KB976569) - Error Code: 0x643



Microsoft .NET Framework 3.0 Service Pack 2 Update for Windows Server 2003

and Windows XP x86 (KB976570) - Error Code: 0x643



Looking back through my Automatic Update history, it appears these two

updates failed a number of time previously too.



My operating environment is:



Windows XP Service Pack 3



I am also attached to a Windows Home Server (approximately Windows Home

Server 2003 SP 1), an HP487 server.



What can I do to get these .Net Framework updates successfully applied?

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 (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://msdn.microsoft.com/en-us/kb/kb00318785.aspx



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.



=========================



What to do if other .NET Framework setup troubleshooting steps do not help:
