SQLServer 2014 Express unattended installation

Hi,

I am trying to install unattended installation of SQL Server 2014 Express. I am using a .vbs script for this.

When the installation is started, first vbs script extracted the setup.exe files on %temp% location. Once files are extracted, instillation is started using configuration file.

But after some time instillation is aborted. In Summary.txt file below logs is found.

Final result:                  Failed: see details below
  Exit code (Decimal):           -2146233052
  Exit facility code:            19
  Exit error code:               5412

I tried to search over internet , but could not found any solution.

Any help appreciated.

Thanks and Regards,
