Mastercam 2021 License Not Found -

Before digging into system files, rule out the obvious:

If you have exhausted this guide, you may have a hardware failure or a corrupted license container.

Before you call your reseller, have this information ready:

Hardware failure: Dongles can die from electrostatic discharge (ESD) or physical damage. CNC Software typically charges a replacement fee (waived if you have active maintenance).

Corrupted license container: In rare cases, the license inside the dongle becomes corrupt. A reseller can remotely re-license the dongle using a WibuCmRau file. Do not throw the dongle away – this is fixable.

As a last resort, the license pointers in the Windows Registry may be corrupted. WARNING: Editing the registry can break your OS. Back up first.
