I am getting the following error "WindowsUpdate_00000643 WindowsUpdate_dt000"
while trying to install "Security Update for Microsoft .NET Framework,
Version 1.1 Service Pack 1 (KB929729). Has anyone else encountered this
problem? If so, have you come up with a resolutuion?

I am getting the having same problem

I too am receiving the same error. Looking for solution as well. Let me know
if anyone can solve this one.

I have the same problem. I updated my Sony notebook to Vista from Windows XP
Pro. I have make a question for Microsoft and they show they will give me a
respond for it. If I "got" it, I will put it on!

One more to the list... two weeks the same, over and over...

I turned off my AVG 7.5 virus control and was able to install the
update the first time without any problem. I had tryed 6 times before I did
this. Might try it.

Is there a less complicated solution? The update seems like its critical one
to have, why is not Microsoft more involved?

I folowed your instructions to the letter and now I am getting error66a.
Anyone else had this problem?

I am not sure about any external product dependencies, but it looks like on
Vista, the .NET updates are very picky about the user which installs the
update. I had tried installing the problematic patch KB929729 as a domain
user through Automatic Updates (check if you are local or domain user) and
encountered the problem. I tried downloading the patch executable to a local
drive and running it with "Run as Administrator" under the same domain user
but still with no success. Finally I logged in as the local Administrator
account (You have to enable it on Vista, since by default it is disabled),
and I installed KB928366 and KB929729 (per one of the posts above in the
thread) manually. It worked with no problems at all and I did not use the
Cleanup utility.

When you try to install an update for the .NET Framework 1.0, 1.1, 2.0, 3.0,
or 3.5, you may receive Windows Update error code "0x643" or Windows
Installer error code "1603"

I had the same issue and I went through the long process of removing all .net
framework 1.1 software from my vista 32 bit computer with the windows
installer clean up utility. After all of this, I still had the same problem.

I found a solution that worked for me. With the .net framework 1.1 software
removed from my computer, I downloaded the following three files in this
order and installed them and it was fine:

Microsoft .NET Framework Version 1.1 Redistributable Package
Microsoft .NET Framework 1.1 Service Pack 1
Microsoft .NET Framework 1.1 Service Pack 1 Security Update for Windows
2000, Windows XP, Windows Vista, Windows Server 2008, Windows 7, and Windows
Server 2008 R2 (KB953297)

By googling these three names, you should be able to easily find and
download these files on your computer.

For those not having removed the .net framework 1.1 software yet from your
computers, you can probably just download this file, install it and hopefully
it will do the trick:

Microsoft .NET Framework 1.1 Service Pack 1 Security Update for Windows
2000, Windows XP, Windows Vista, Windows Server 2008, Windows 7, and Windows
Server 2008 R2 (KB953297)
