Windows update fails with error code 0x643

Anonymous

I have downloaded the recent Microsoft updates and all but one installed successfully. The failing update was: 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);

with an error code of 0x643.

We tried several times to install it and it keeps failing. It was originally the 3rd update in the list to install. After failing the first time, it was the only one we were trying to install. We tried it after the restart required for the other updates.

I successfully installed SP3 to XP Home Edition and shut down when it asked me to restart. Shut down dialogue box said it would install three items as I shut down; wasn't sure if it was referring to the SP3 install or to 3 automatic updates "waiting" at the time of the SP3 install, which I was holding off on until the SP3 install was in place. I allowed the install and got an error message on the first: "NDP1.1sp1-KB953297-x86.exe application error; the instruction at "0x01016BED" referenced memory at "0x00000004." The memory could not be read." Choices were to terminate or debug; chose debug. It went on to install the other two items. Started up and got a related error message: "NDP1.1sp1-KB953297-x86.exe encountered a problem and needs to close." Gave the time of the error and offered to send an error report for me. Shut down and started up twice more and did not receive the error message. Looked up the KB article, which referred me to security bulletin MS09-061 describing .NET Framework 1.1 service pack issues and qualifying them as Critical. I've verified that I have .Net Framework 1.1 installed per the article, but I'm in over my head when it comes to this type of problem. I had issues with NET Framework during disk reformatting a few days ago, so I know I don't want to mess with that if I don't have to. Hoping either (a) I can ignore the problem in the absence of continued error messages or (b) that I can simply restore to the point prior to the SP3 install and just live without it. Am I being ignorant in either of these based on the nature of the error?

I reinstalled Microsoft .NET Framework 1.1 Service Pack 1.

Worked for me!

Oh bless you, Marnix. That worked for me too. Finally. All the other solutions listed here were so appallingly cumbersome, I finally just refused the update and figured I'd get along without it. But yours actually sounded sensible and do-able, and yes, it worked. The system was looking for one file in the wrong place during the reinstall, but I searched, found it and re-directed the program. Went to Microsoft updates and re-allowed the update, it ran this morning with no indigestion.

I bow to you.
