Update KB950749 and Error Code Dx80070005

I'm new to computers and this group. I have Windows XP Pro with automatic
update set. Automatic Update KB950749 failed to install today and yesterday.
When I click the "failed" icon, I get error code Dx80070005. I see there are
options to find out what is wrong - but when I try these I run into dead
ends. For example, I see in one spot that there is no Microsoft charge for
update issues - but elsewhere I get the message that my computer is not
eligible for this and that there will be a $59 charge. I encountered other
frustrations.

Is there an easy answer to my problem?

 

Tip: Temporarily disable real-time protection by your anti-virus and/or
anti-spyware applications (e.g., CounterSpy, Spysweeper, Spybot, AVG
Anti-Spyware) and/or any third-party firewall (e.g., ZA) before attempting
to install the update(s). If you disable a third-party firewall, do NOT
connect to the internet without having the Windows Firewall enabled!

See if you can install it manually:
