Does it have its own installation procedure?

If no, I'd copy that add (assuming it's a .xla file) to its own folder on my C:
drive.

Then I'd open excel (xl2003 for me), then use:
tools|addins
and browse to that folder and select the addin.

You could also store the addin in excel's favorite location for addins.

For me (xl2003 and winXP Home):
C:\Documents and Settings\(username)\Application Data\Microsoft\AddIns\
