As
add-ins are revised, dates and the purposes of the revisions
are listed below. To check the version
of the add-in that you are using, find the date of the
add-in by choosing the About Add-in item on the submenu
for the add-in. Add-ins that do not have a submenu, LP
Solver and Net Solver, have an About Add-in button on
the dialog for the add-in. Clicking this button reveals
the version date.
If you find that you are using
an older add-in than is available at this site, download
the add-in. Add-ins are stored in the zip format, so you
will have to un-zip the file. Once unzipped, replace any
old add-ins of the same name. Otherwise, Excel may use
the old version rather than the new. |
