I have a macro that I want to share with other users on my network. I went
through all of the steps to create an addin and it works fine on my system,
opens with every workbook, etc. but I can't figure out how to get it to work
on someone else's machine.

I emailed him the addin file and saved it to the same folder on his machine
that it was on mine (c:\documents and settings\...\application
data\microsoft\addins) and when I opened up his Excel I went to tools,
addins, browsed to find this file, and checked the box next to it.

But when I try to run a macro, it says none are installed. The addin
contains one macro, but it's not showing up on his computer ... ? What am I
not doing right?
