This is a <strong>required update<\/strong> that will enable the software to switch to node-locked activations and deactivations. Node-locked licenses associate your software with a specific machine, allowing administrators to monitor who is currently active.<br><br>In addition to managing your license directly from the software, you will have the capability to deactivate license keys remotely through the \u201cMy Account\u201d portal (View Licenses -&gt; Manage Sites). This will be helpful recovering lost seats, e.g., when a PC is decommissioned without prior deactivation.<\/p>\n\n\n\n<p>This new licensing system will be fully implemented by the end of March 2026 and will necessitate that existing active users re-register, which will attach the machine name and Windows username to the license key. This is a one-time activation and will not be counted against the total permitted activations.<\/p>\n\n\n\n<p>If your software fails to register it may mean that it has not been updated to the latest version. Click [Use Trial] instead.
