Question :

I tried to install sql server 2017 on windows server 2019 but the following error appeared to me:

There is a Problem with this Windows Installer package. A DLL required for this installation to complete could not be run. Contact you support personnel or package vendor.

Here are the solutions that I have tried that did not work!

  • Update Windows
  • Uninstall then reinstall SQL Server 2017
  • Completely change installable “another SQL Server 2017, SQL Server 2014, SQL Server 2019”.
  • I tried to install the English version
  • I checked the administrator permissions on the file c:/windows/utilisateur/appdata/local/temp, it has total control.
  • I checked the administrator permissions on registry editor/HKEY_LOCAL_MACHINE/CurrentControlSet/services/msiserver/security, it has total control.
  • I copied the file dll (sqlncli11.dll) into syswow64 and system32.
  • I also checked the system files with the command sfc/scannow to see if there are any corrupt files.
  • And when I install I always run as administrator.
