Problem with using ExpressMaint with Microsoft SQL Express 2012

If you are trying to use ExpressMaint with Microsoft SQL Express 2012, you will most likely run across the following error:

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.SqlServer.Smo, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.

This is easily repaired by installing the following items (as appropriate for your system architecture):

Microsoft® System CLR Types for SQL Server® 2008 R2

Microsoft® SQL Server® 2008 R2 Shared Management Objects

All of these items are part of the Microsoft® SQL Server® 2008 R2 Feature Pack
