I've write an application for testing RDA Syncronization

When i try to connect to SQL Server 2005 Express for rda pull i've an error:

The version of the Microsoft OLE Db Provider for SQL server is not connect.
Install MDAC 2.8 or later. [600,version = ]

I've Windows Vista, Visual Studio 2005 Sp1 + Sp for Vista, Sql Express 2005,
SQL Compact Edition (SQL CE 3.1).

I've write

private string rdaOleDbConnectString = @"Provider=sqloledb.1;Data
Source=192.168.1.63,1433;Initial Catalog=GestioneClientiSQL;User
Id=sa;Password=pippobaudo;";

private string rdaUrl = @"http://192.168.1.63/sqlce/sqlcesa30.dll";

private string localConnection = @"Data Source=\My Documents\Archivio.sdf";

How can solve my problem?
