I have a NAnt-based script which that I run on my local PC that connects to SQL Server 2008 Express also running on my local PC to drop and recreate databases using .sql files - this works fine, no problem here.

The problem comes when I have recreated the same set-up on another PC, I get the error in my NAnt script saying that:

System.InvalidOperationException: The 'SQLNCLI' provider is not registered on the local machine.

I have searched online and have found that in a forum it was suggested that I needed to install the Microsoft SQL Server Native Client, and got it from this URL. (Admittedly, I have only installed the Native Client part of this)

Despite this being installed on my second PC, the script still gives me the same error. Any suggestions?

The correct provider for SQL Server 2008 is SQLNCLI10.1.
For SQL Server 2012, that would be SQLNCLI11. (source)

Sadly, the migration to 2008 did not pick up the change...
