License Not Found | Gt Designer

If the software was installed using a temporary or incorrect product key, you must re-input your valid Mitsubishi license.

To understand the gravity of this error, one must first appreciate the context in which GT Designer operates. Unlike consumer software, industrial automation tools control physical processes—assembly lines, power generation, and water treatment facilities. When an engineer or technician launches GT Designer to modify a process screen or troubleshoot a machine fault, they are performing a time-sensitive task. The appearance of a license error in this environment introduces a variable that can cascade into significant downtime. The error effectively severs the user's access to the project files and the logic governing the HMI, rendering the technician powerless to enact necessary changes until the licensing issue is resolved.
