I suspect that the add-in was part of the original template download.
Templates are often uploaded by users rather than being made by Microsoft, so
it could have been a file that the original author built.

Have you tried checking in the list of Add-Ins to see what information is
there? Office Button - [Excel Options] and then click the Add-Ins link in
the left pane.

You could do a search on your system for *.xla files and see if the original
add in is laying around. Then I'd try turning it into a .xlam file and
installing that as part of your invoice template.

I have been using a template created in Excel 2000 for my business invoices
for 7 years. This template had a tool box which allowed me to assign a
sequential new number for each invoice automatically by clicking assign new
number. Is this feature available in Excel 2007? I have tried enabling
macros which were used on the previous version, but each time I attempt to
run them, I get the message "The numbering add-in must be loaded for optimal
numbering and toolbar behavior. Please load this add-in into your Library
Directory." Where do I find this add-in? It is not located in Excel 2007 and
I cannot find it on available downloads on Microsoft web-site... which is
where I am directed from the help menu. PLEASE HELP!!
