We have new machines that are now throwing this error:

Exception Message is:: Generic exception thrown at step:: DataAccessFunctions::getImportSpectSpreadsheet::Execute importss.  Exception Message is:: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

We have changed the platform in VS2005 to x86 and the issue occurs.

It works ok on WIndows XP with Office 2007 installed, however the error message above occurs when on windows 7 64 bit and Office 2010.

We have attempted and installed the Microsoft Access Database Engine 2010 Redistributable attempting to repair the issue.  Here is the code, it should be noted that we have attempted variations :

Provider=Microsoft.ACE.OLEDB.12.0, Extended Properties=Excel = 8.0
Provider=Microsoft.ACE.OLEDB.14.0, Extended Properties=Excel = 08.0
Provider=Microsoft.ACE.OLEDB.14.0, Extended Properties=Excel = 12.0




    Public Function importSS(ByRef filepath As String) As DataTable
        Try
            Dim strConnection As System.Data.OleDb.OleDbConnection

            Dim dsData As New DataSet
            Dim dt As New DataTable
            Dim objAdapter As System.Data.OleDb.OleDbDataAdapter

            strConnection = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0; Data Source='" & filepath & " '; " & "Extended Properties=Excel 8.0;")
            strConnection.Open()
            dt = strConnection.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, New Object() {Nothing, Nothing, Nothing, Nothing})
            objAdapter = New System.Data.OleDb.OleDbDataAdapter(String.Format("SELECT * FROM [{0}]", dt.Rows(0).Item("TABLE_NAME")), strConnection)
            Dim dt1 As New DataTable
            objAdapter.Fill(dt1)
            Return dt1
        Catch ex As Exception
            Throw ex
        End Try
    End Function

Thanks for any help you can provide

I am not 100% sure, but if you have 2010, then you can't use the 12.0 library, you would need to use the 14.0 provider.  It might be possible to find the 12.0, if you start with the 14.0, and then let the probe find the correct version from there...
