I'm getting an exception while trying to open a OleDBConnection.

I'm developing a win app under Vista 64bit environment. The file's suppose to open an excel file, and bind it to a datagridview.  The code below is throwing the following exception:

ServerVersion 'oleDbXLS.ServerVersion' threw an exception of type System.InvalidOperationException'      string {System.InvalidOperationException}

When it's trying to execute:

oleDbXLS.Open();

I've been researching the whole night and I can't find any answers. Help!

private DataTable get_data_from_excel(string _strFullFilename)
{
     OleDbConnection oleDbXLS = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;" +
          "Data Source=" + _strFullFilename + ";" +
          "Extended Properties='Excel 8.0;HDR=Yes;IMEX=1';");
     OleDbCommand OleDbcomSelect = new OleDbCommand(@"SELECT * FROM [Employee Information]", oleDbXLS);
     OleDbDataAdapter OleDbdaMain = new OleDbDataAdapter();
     DataTable oReturn = new DataTable();
 
     try
     {
         oleDbXLS.Open();
         OleDbdaMain.SelectCommand = OleDbcomSelect;
         OleDbdaMain.Fill(oReturn);
     }
     catch (Exception e)
     {
     }
    finally
    {
         oleDbXLS.Close();
         OleDbdaMain = null;
     }
 
     return oReturn;
}
