I've created a workbook that has several macros which are linked to excel menu items. I am trying to programatically save this workbook as an addin to my xlStart folder. However, the bit of code that I'm using doesn't seem to be working correctly (or at least how I thought it would). What I thought would happen is that this addin would open up in the background. However, everytime I open up Excel, the workbook opens up. Is this because it is saving as an Excel workbook and not an addin? Any ideas?

Application.DisplayAlerts = False
fName = "C:\Program Files\Microsoft Office\Office\XLStart\Custom.xla"
Call ActiveWorkbook.SaveAs(fName, xlAddIn)
Application.Quit
