Hi @jespa007, okay thanks for the clarification. You should be able to download the DLL for the Stream Engine API directly on the download section @ https://developer.tobii.com/consumer-eye-trackers/stream-engine/getting-started/
“Download Stream Engine for Consumer Eye Trackers”. This Link was still working as of this post with the relevant DLL’s inclued in the ZIP file.
Certainly, I will pass along your input regarding Pro and Core SDK interoperability to our development team for review. Please do let us know if we can provide any further information for your needs. Best Wishes.
