ParticipantI have created a Unity game using Tobii 4C. The games run well in my development machine.
When copied to another Windows 10 Pro, eye tracking in not running in the games. It says it cannot connect with the device. Note that, the device software has been installed and successfully running in Windows system.
Please help!!!

KeymasterHi @ltha, sorry to hear about your issues. It may be worth ensuring you have VC Redist Packages installed.. which versions do you have installed on the remote machine?
Also, if you could kindly send us detailed Unity logs during game launch without eye tracking, that would be most helpful. Thanks and best wishes.

Participant(Sorry, there are some typos in previous post. Please read this one)
Thank you very much for your reply,
We have installed Unity and copy game source to both machines (Development and target machines) and run the game in both build and Unity editor modes. We have found that:
Both machines:
– OS: Windows 10
– Unity: 2019.2.15f1
– Tobii eye tracker 4C works perfectly in Windows.Development machine:
– Tobii eye tracker 4C works perfectly in Windows.
– The demo Unity eye tracking scenes works perfectly
– Unity variables:
+ TobiiGameIntegrationApi.IsTrackerConnected(): true
+ TobiiGameIntegrationApi.GetTrackerInfo().FirmwareVersion: 2.27.0-4014648Target machine:
– Tobii eye tracker 4C works perfectly in Windows.
– The demo Unity eye tracking scenes says “No Gaze Detected”
– Unity variables:
+ Host.isConnected: false
+ TobiiGameIntegrationApi.IsTrackerConnected(): false
+ TobiiGameIntegrationApi.GetTrackerInfo().FirmwareVersion: 0It seems that the tobii_gameintegration_x64.dll could not connect to Tobii firmware on the target machines. We have also test with some other machines (same configuration). This problem seems to happen randomly on these machines.
Please help, thank you very much.
