Hi,
Could you follow the workaround given in below Stackoverflow link
installing-sql-server-2016-a-dll-could-not-be-run-error-code-1723
If you have old SQL Server native client installed, please uninstall it completely and do a fresh install. The setup is failing while installing SQL Server native clinet. If nothing helps post content of C:\Program Files\Microsoft SQL Server\140\Setup Bootstrap\Log\20200831_202936\sqlncli_Cpu64_1.log
on shared drive and then share the link here
