Hi @greatdsa, thanks for your query. As you have stated that you have purchased the Tobii Analytics Licence which grants you usage of the Tobii Pro SDK in conjunction with the 4C Eye Tracker, then this entitles you for support with the Tobii Pro Business Department.
Please kindly raise a ticket with Tobii Pro Support directly regarding this issue @ https://www.tobiipro.com/contact/support/ and they should hopefully be able to assist you as I am afraid I have not encountered this error before however they may have seen such a problem previously.
Apologies for the inconvenience and good luck in resolution!
