title: How can I instruct excel to execute my .xla file automatically on startup?
body: <p>I have a .xla located at C:\Program Files\Microsoft Office\Office14\excel-udf-concat.xla that I need to execute upon start up</p>
  
  <p>At the moment I must load excel first and then manually execute that file, sometimes I forget to do this and my formula does not get executed!</p>
  
  <p>Is there a way to instruct excel to do this?</p>
