Stephen,

I think this is a Windows feature not Excel.

Why don't they detect? If they open the newer one, problem solved? If they
don't, the date is not modified? Don't quite see the problem.

I have an Excel add-in that runs from the users PC and
checks a network location for a newer version of itself
each time it runs. If the network version's file modified
date is newer, it calls a batch file to replace itself.
The problem is, as I was testing it, I realized Excel
changes the file modified date of my add-in when it is
loaded and then changes it back as soon as Excel is closed
and the add-in is unloaded. Thus, when I put a newer
version on the network, no one's PC versions will detect
it as newer. All I found in the kb was #245420 and it
doesn't give me a workaround. Any ideas?
