Hi Mohammed @mnabizadeh, the Tobii Tracking software v2.8.0 belong to the Tobii Pro business department.
This forum is intended for support with the Tobii EyeX and C4 Eye Tracker and associated SDK’s.
Please get in touch with Tobii Pro support directly @ http://www.tobiipro.com/contact/contact-support/ for an answer
to your query.
EDIT: [Jenny, 03 May 2017] – The above information is wrong. Tobii Eye Tracking Software v.2.8.0 is the latest software for consumer eye trackers like Tobii Eye Tracker 4C and Tobii EyeX Controller. I will ask someone from the Tobii Interaction Engine team to look at the original question.
