Autocad 2024 Lt Serial Number. If you see licence details on the product details page, select it to display your serial number and product keys. My thought is that since @davidd8uzc op was in may and 2024 lt was released at end of march that the 2023 lt trial version most likely was downloaded just prior to that date.
This reference, along with the product key and license type, can be accessed. A serial number is a unique identifier provided by autodesk.
