iPhone opening excel file SSIS execute small console application

I have encountered the problem of iPhones and iPads not opening excel attachments. I get a gray image with the name of the xls file. If I send xlsx I get one blank box. I have learned that if AFTER I create the excel file with SSIS, I open the file with excel, refresh and save then close the file, then use dbsendmail to attach the xlsx it will open fine. I am getting an error though that says "Can't create activex object" when I run the stored procedure that includes calling the windows exe below. It runs perfectly if I double click it. I also tried running it as an execute process task and it fails with the can't create activex error. Why can't I run this with a stored procedure or SSIS Process task?

        ' Create an Excel instance

        oExcel = CreateObject("Excel.Application")
        ' Disable Excel UI elements
        oExcel.Visible = True
        oExcel.DisplayAlerts = False
        oExcel.AskToUpdateLinks = False
        oExcel.AlertBeforeOverwriting = False

        oWorkbook = oExcel.Workbooks.Open("D:\export\temp\aDailyTransfer.xlsx")
        oWorkbook.RefreshAll()
        oWorkbook.Save()

        oExcel.Quit()
        oWorkbook = Nothing
        oExcel = Nothing
