MAP Toolkit Installation not Detecting Instance of SQL

Hi,

I am trying to install v7 of the MAP toolkit using an existing SQL 2008 R2 database.

I have created a new Instance called MAPS as required and ensured the Server Collation is set to SQL_Latin1_General_CP1_CI_AS.

When I run the MAP setup the Installation Summary si still saying it will install microsoft SQL Server Express LocalDB.

Why is this?  The MAPS instance is running and I can connect to it with SQL Manager so I know the DB is there.  It is on the same server also.

I beleive I have done averything that the FAQ and Getting Started Guide suggests but it still does not work.

Any ideas why this is not working?

Thanks.

Rob
