I am using a barcode scanner, scandit 5.14.2 on Linux with a trial license. I am trying to run a python module sample i.e. CommandLineBarcodeScannerImageProcessingSample.py but I am getting the following error

Processing frame failed with code 15: The Scandit SDK license
  validation failed. Your app ID does not match the license key's app
  ID.

I have tried creating a new license key with Application ID / Bundle ID as the name of the file i.e. CommandLineBarcodeScannerImageProcessingSample.py but still getting the same error.
Same goes with CommandLineBarcodeScannerCameraSample.py but all c scripts run fine.
In FAQs of scandit it is mentioned that I should use program_invocation_name as bundle id. Is there something I am missing? Any suggestion would be very helpful
I know it´s a little bit late, but I think I found a solution for the problem.
I experienced exactly the same issues and could fix it with creating a new licencse key with the Bundle ID 'python3'. Then you have to use the generated license key in your python samples.
Let me know if that worked.
