FaceSDK is a copy-protected library, and must be activated with a license key before its use. You need to pass the license key received from Luxand, Inc. to the FSDK_ActivateLibrary function before initializing Luxand FaceSDK. Almost all FaceSDK functions will return the FSDKE_NOT_ACTIVATED error code in case the library is not activated. To retrieve your license information, call FSDK_GetLicenseInfo. This function returns the name the library is licensed to. You may need to use the FSDK_GetHardware_ID function to obtain your hardware ID if your license is restricted to one machine only. Additionally, you can find out hardware ID by running the hardwareid program (ShowHardwareID.exe for Windows), which is located in the bin directory.
To get a temporary evaluation key from Luxand, Inc., run License Key Wizard from the Start – Luxand – FaceSDK menu. You may also request this key at
