If you cancel your Update Subscription, you will revert to the latest allowed version you purchased before subscribing to the Software Update. You can check the latest allowed version for each license in your organization on the License page in MyCAD. You can find installation kits of your lifetime license in the Installation kits section of MyCAD. Please note that files created with the new version of the software are not readable by old versions, so we strongly advise you to save your models with Save as compatibility mode functionality. The functionality will allow you to save your files (models, orders) in a software version of your lifetime license and keep important data intact.
