Error message when you try to create a new subscription in SQL Server Express: "Invalid column name 'step_uid'."

Consider the following scenario. You upgrade an instance of Microsoft SQL Server Desktop Engine (MSDE) 1.0 or an instance of SQL Server 2000 Desktop Engine (MSDE 2000) to SQL Server 2005 Express Edition (SQL Server Express). On the upgraded instance, you try to create a new subscription by using one of the following methods:

• In SQL Server Management Studio, you use the New Subscription Wizard that remotely connects to the instance of SQL Server Express.
• You use Replication Management Objects (RMO) or you use Transact-SQL stored procedures if the subscription is enabled for Microsoft Windows Synchronization Manager.

In this scenario, you may receive the following error message:There are other scenarios where you may experience similar symptoms, such as attaching or restoring a replicated database from an instance of MSDE to an instance of SQL Server Express.

This problem occurs because the msdb database is not upgraded when you upgrade from MSDE to SQL Server Express. Replication or subscription in SQL Server Express expects the upgraded schema for the msdb database, but no match can be found.
