    Windows Defender Antivirus - KB4052623 4.18.1910.4 - Error 0x80070643


    Hi everyone,
    i got error 0x80070643 when I try installing last antimalware platform, I had the same error last time but it installed in some way, now it seems impossible.
    Windows update troubleshooter didn' find errors.
    SFC /SCANNNOW found corrupt files but was unable to fix some of them. In the cbs log file I see error in windows platform.
    I resolved some errosr with:
    Dism /Online /Cleanup-Image /CheckHealth
    Dism /Online /Cleanup-Image /ScanHealth
    Dism /Online /Cleanup-Image /RestoreHealth

    but i'm still unable to solve the problem.
    Thanks.

    :)

    Win Defender KB4052623 (v4.18.1905.4) repeated install fail 0x80070643

    Can someone please tell me more about this situation? This Windows Defender update is repeatedly failing to install: KB4052623 (Version 4.18.1905.4) installation fail with Error 0x80070643. I have searched various forums for a solution, but have found none so far that pertains to this specific version.

    Also, when I try to manually update Windows Defender from within Windows Defender, I get another error message saying: error code -2147023293 protection definition update failed.

    Thanks in advance for any help provided. I should add that I have no 3rd party AV installed.

    Here are the respective screenshots of the error messages:
