C++ Static Library

The KEYZY C++ Client Library is a static library that you link into your application to handle license activation, validation, trials, and upgrades. It supports online, semi-online, and offline activation schemas.

Latest Version

Download C++ Client Library v1.10.2 (Windows, macOS, Linux)

Warning: product released on a version before 1.10.0? Do not just rebuild with the new library. The default Host ID scheme is V2, so every device’s host id changes and all existing activations would have to re-activate. Keep the default and call migrateHostIdV1toV2() on every start instead: see Move a Released Product to Host ID V2.
