plexusOne Network Toolkit includes several tools which help you to manage, troubleshoot, maintain and monitor your network. Purchasing a license for plexusOne Network Toolkit provides access to updates for this version (i.e. 1.x), with substantial discounts for upgrades to the next major version (i.e. 2.x). Support is available via our website, or by email. License files will be emailed to you within 24 hours (normally much less) of receipt of order. You will need your Hardware ID, which is displayed in the Trial Information window, or alternatively in the About window which is available on the Help menu. Your license will be "tied" to your computer, so ensure the Hardware ID you enter is correct. Discounts are available for users who wish to purchase two or more licenses (for example, one license for a desktop and one license for a laptop). If you change your computer at any point, please email support@plexusone.com to have your license transferred. Please note - if you wish to purchase more than one license, please enter only the first Hardware ID. After we have received your order, we will contact you by email for a list of further Hardware ID's - you do not have to use all licenses immediately in this case (i.e. if you purchase 10 licenses but only require 8 at the moment, we will hold 2 for you until you require them). If you have any special requirements, please do not hesitate to contact sales@plexusone.com.
