Not registered error message   

Hi,
I am trying to deploy a really simple application built on Visual Studio 
2008 using framework 3.5 that consumes an Access 2007 database.
When I deploy it and run my app, I get the following error:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine

Here is the code that's causing the error:
private void ConnectToDB()
    {
      try
      {
        if (_dbConnection.State != ConnectionState.Open)
        {
          _dbConnection.ConnectionString = 
global::MCIS0685.Properties.Settings.Default.MCIS0685DBConnectionString;
          _dbConnection.Open();
        }
      }
      catch(Exception ex)
      {
        MessageBox.Show("Unable to connect to database. Error:\n" + 
ex.Message,
            "Database Connect", MessageBoxButtons.OK, MessageBoxIcon.Error);
      }
    }
The connection variable is defined as:
private OleDbConnection _dbConnection = new OleDbConnection();

This is the configuration file:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
    </configSections>
    <connectionStrings>
        <add name="MCIS0685.Properties.Settings.MCIS0685DBConnectionString"
            connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data 
Source=MCIS0685DB.accdb"
            providerName="System.Data.OleDb" />
    </connectionStrings>
</configuration>

The DB file is in the same folder as the executable assembly.

Any ideas?
TIA
