Symptoms
The error "ABBYY FineReader Engine is not licensed" can appear during the launch of one of our samples.
Cause
This issue is often related to the incorrect parameters in the InitializeEngine method call.
Resolution
If you are trying to run one of our XCode samples, you need to ensure that the correct projectID value is specified in the Engine.mm file. If you are using an online license, the licensePath and licensePassword parameters should also be specified there.
For other samples, the same variables should be specified in the SamplesConfig.h header file.
