    Hi,

    The error code 0x80070643 is commonly caused by .Net Framework installed on the computer. We suggest addressing the 0x80070002 error code first because this issue occurs when some files in the Windows Update are missing. We can solve this error code by following
    the troubleshooting steps suggested on this article.

    Note: The troubleshooting steps for Windows 8.1 also applies to Windows 10.

    Update us with the outcome so we can provide further assistance.
