BizTalk 2009: Unable to configure BAMArchive

When trying to configure the BAMArchive database on a fresh BizTalk 2009 64 bit install, I encountered the following error:
Microsoft SQL Server 2008 Data Transformation Services (DTS) for BAM Archiving is not installed on the local machine. Please install Microsoft SQL Server 2008 Integration Services.
...
Could not load file or assembly 'Microsoft.SqlServer.ManagedDTS, Version=10.0.0.0,

This error makes it sound like you need to install SQL Server Integration Services (SSIS) which is a little misleading.

The documentation on MSDN indicates the following:

What 64-bit SQL Server components are required to configure BAM tools?
The configuration wizard is a 32-bit process; therefore it requires certain components which allow it to communicate with 64-bit SQL Server. You must install the following SQL Server client components to enable configuration of BAM tools:
Connectivity Components
Management Tools
Legacy Components

In order for me to complete my installation, I installed the following components from the SQL Server 2008 media(I don't see the Legacy Components option).
