Defender update failure

[Guest]

I just installed Defender (at Windows request), and it immediately said it
needed to update it's files. It failed to do that, so I shut it down and
then restarted. It did the same thing, so I clicked on the "view
troubleshooting tips on the web." I followed the instructions on that
website (to run: Msiexec /x {A5CC2A09-E9D3-49EC-923D-03874BBD4C2C}), but it
didn't make a difference. When I run Defender, it says my definitions
haven't been updated in 103 days, but when I click on the "check now" button
it doesn't do anything for a few minutes and then eventually gives me an
error saying "Windows Defender was unable to complete the update: 0x80072efd"

Yes, I run WinXP Pro SP2 with Office 2003, and the auto-update features run
just fine. My Defender is listed as the following: Defender Version
1.1.1347.0, Engine 1.1.1303.0, Definition 1.0.0.0

*** Help fix this product that Windows downloaded that I didn't even need! ***

Well try this:
“Windows Defender definitions haven’t been updatedâ€
http://support.microsoft.com/kb/918355

Error message after you reinstall Windows Defender Beta 2: “Windows Defender
definitions haven’t been updatedâ€

I have the exact same problem. I'm running windows 2000 sp2, I also have
autoupdate on. The error I get is that "there are no updates available".
That doesn't seem possible.
Need some help here...

I got this from another post. It worked!


http://www.download.windowsupdate.c..._5d423c0277b7bab707f7c87273d8fb805b163eb2.exe

Just download that and execute it.
Good luck...
