ENindexer is a per user license.That means each license is assigned to a unique user who is then free to use the software on as many machines as they would like. This means a single user can install to a copy on a single desktop machine, a desktop and a laptop, 3 laptops... We don't care. However the software is only licensed for that particular user. For multi-user licenses, contact us at firstname.lastname@example.org for more information on licensing options.
NOTE: You must do an installation of the software on each machine you want to use it on. You cannot copy the installation directory from one machine to another as there is setup work done in the installation process that would not be picked up by a copy. Once the software is installed, use the same key information from your original purchase on the new machine to get past the 100 name trial limit.
