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.

    Hi Dan,

    I am not used to security bulletins from Microsoft. I understand that they have corrected the vulnerability of updated KB 974417 BY mso9-061. But I did not understand what i have to do on my machine to be able to successfull install KB 974417. Is there something that I have to download (KB 974378) or something which will let me install this update. If yes, please advice/provide link of where can I download that.

    MS09-061 looked like a text written to read but nothing to install (according tome)!.

    Please help.

    Regards,

    Pratik
