    Go to Settings > System > Troubleshoot > Other troubleshooters.

    Run the Windows Update Troubleshooter.

    Open Command Prompt as Admin and copy-paste the following commands entering Enter key after each.

    net stop wuauserv

    net stop cryptSvc

    net stop bits

    net stop msiserver

    Navigate to:

    C:\Windows\SoftwareDistribution\Download

    Delete all its content.

    Open Command Prompt as Admin and restart the service:

    net start wuauserv

    net start cryptSvc

    net start bits

    net start msiserver

    Hi Kirtan,

    Thanks for your post. Error code 0x80070643 typically indicates an issue with the installation process, possibly due to corrupted system files . Once restart the computer and download the installation file again and install.

    You can offline download the update with the following article:

    CVE-2024-37341 - Security Update Guide - Microsoft - Microsoft SQL Server Elevation of Privilege Vulnerability

    If no help, try the following methods to repair the system.

    Step 1: Press Windows + R to open the Run dialog.

    Step 2: Type cmd in the text box and press Ctrl + Shift + Enter to run Command Prompt as an administrator.

    Step 3: Type these commands. sfc /scannow (and press Enter) Dism /Online /Cleanup-Image /ScanHealth (and press Enter) Dism /Online /Cleanup-Image /CheckHealth (and press Enter)

    The DISM tool will report whether the image is healthy, repairable, or non-repairable. If the image is repairable, you can use the /RestoreHealth (Dism /Online /Cleanup-Image /RestoreHealth) argument to repair the image.

    Best Regards,
