Updating a Software License
When a software license is activated for Mastercam, the end date for maintenance is saved with the activation. The end date determines whether a new release can be installed as only software released while the license maintenance is active will be allowed to operate. You may need to update your software license when you upgrade or after renewal, particularly for maintenance releases. To update a software license, you need to activate the software license. See how to do this here.
If the software license is being updated on the same computer it is currently activated on, you do not need to deactivate it first. However, if you plan to move the software license to another computer when updating it, you must deactivate your license before updating and reactivating it on the new location.
To confirm the current end date for the activated license, open Mastercam and go to File > Help.
