Answer 2

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,

Ian Xue
