    Hi,

    Post summary log, please. Maybe installation package is corrupted or the issue is related with .NET Framework version.

    Thanks

    You find installation logs in C:\Program Files\Microsoft SQL Server\150\Setup Bootstrap\Logs where there is one folder for each installation attempt. It is probably the file for SQLncli you look in. Maybe there is a hint which DLL that is missing. (Although I have feeling that it is not - this error seems familiar.)

    Hi @Bashar Kheir ,

    Could you please share us SQL Server Setup log within %programfiles%\Microsoft SQL Server\nnn\Setup Bootstrap\Log? (nnn=150 for SQL Server 2019, 140 for SQL Server 2017). Please refer to View and Read SQL Server Setup Log Files.

    And please make sure you have enough permission on “C:\Users\username\AppData\Local\Temp” folder.

    In addition, according to my research, this error may be related to sqlncli.msi. Here is a solution from this blog. On opening the sqlncli.msi file using ORCA editor and searching for SNAC_SetClientSSNLDefaults_32 key, and then change the value $DP_sqlncli11_dll_32 = 3. Please check if this solution is suitable for your issue.

    Best Regards,
    Amelia
