sql-server-2005 ssis

Question

Tengo el código VB para convertir .xlsx a .pdf en SCRIPT TASK. Cuando ejecuto la tarea, se ejecuta correctamente sin errores. Pero el archivo de Excel no está convirtiendo al formato pdf.

He agregado la referencia de Microsoft.Office.Interop.Excel a la tarea. Por favor mira el siguiente código. No podría saber cuál es el error en esto.

Por favor ayuda. Gracias por adelantado.

Imports Excel = Microsoft.Office.Interop.Excel
Imports System.IO
Imports System.Data.SqlClient
Imports System.Text
Imports Microsoft.Office.Interop.Excel
Imports Microsoft.SqlServer.Dts.Runtime
