Consider the following scenario:

  • You have a Microsoft SQL Server Integration Services (SSIS) 2012 or SQL Server Integration Services (SSIS) 2014 project.

  • You set the ProtectionLevel property of the SSIS packages to EncryptSensitiveWithPassword.

  • You create a SQL Management Object (SMO) connection manager for the project.

  • You set a user account and a password for the connection manager.

  • You run the SSIS project.

In this scenario, you receive the following error messages:

Microsoft.SqlServer.Dts.Runtime.DtsException: 'Salt' attribute for PassWord is missing in the project manifest.
