    Not able to Install Update Microsoft .NET Framework 3.5 (KB951847) x64, Windows Update Encountering Unknown Error Code 643

    I am working on Microsoft Windows Vista 64-bit with Service Pack 2 (SP2) on an HP Notebook PC. I am not able to install update .NET Framework 3.5 Service Pack 1 as well as .NET Framework 3.5 Family Update (KB951847) x64. Windows Update prompts a reportedly unidentified error code 643 in addition to the update fails. So please if anyone knows how to get out from this problem then please suggest me about this over here.

    From my opinion you have to utilize the .NET Framework automatic cleanup tool. So try this may you got solution to your problem or you are able to make Enable Microsoft Installer logging as well as Windows Update verbose logging. You have to attempt to install updates once more to generate the log files. You have to disable Microsoft Installer logging as well as Windows Update verbose logging.
