I am sure this is an easy answer.  We have been using SEI (only the Excel Addin) for many years - same 2 users and computers.  No issues.  Recently a few other users have a need to use SEI.  My issue is when a different computer (which has the SEI Addin installed) opens the Excel file with the SEI formula - it does not update as the Process/Environment reference (under formula Editor) is "blank".  Once I configure the reference manually - it works perfect.  So my question is what is best practice for setting up an Excel worksheet using SEI on many different computers?  Do I really have to manually configure the reference on EACH computer using SEI?  I assume the reference has to be EXACTLY the same of EVERY computer?  I think there is an easier way.  Thanks.
