I am looking for a way to install an Add-In from Excel without using
one of the professional install build applications. I'd like for the
user to to be able to open a workbook (or double click) that has an
install button located on a Menu tab. Once pressed, the VBA would then
install the appropriate Add-In(s). Any one have any code that will do
this? How about the add-in itself, if double-clicked (opened) can it
install itself as an add-in?

I've searched for some code, but it looks like most are using the
install-wise type software.

Regards,

TWB
