Do you mean that you've created a package that installs SQL Express and then runs a package to create a database?

It sounds as though the credentials that you've set SQL Server Express up with don't match up with the options that you have chosen in SQL Packager can you make sure that the server instance name is the same for the SQL Server Express Instance and the package.
