I jumped into the discord and got this answer from a helpful user and so far it seems to have solved the issue!
Sometimes it is necessary to perform a clean reinstallation of the Tobii Core software if something has gone wrong or files have become corrupt. To perform a reinstallation, please do the following:
– Uninstall the Tobii Core software through Programs and Features
– Open up Device Manager and remove the relevant hardware, but do not allow the machine to reboot yet:
— For a 4C/IS4 platform, find the USB Devices section, then remove the EyeChip device
— For an EyeX/IS3 platform, find the Eye Tracking Devices section, then remove the EyeX Controller device
– Open the registry editor (in a Run box, type regedit and click OK) and then delete the following keys:
— HKEY_CURRENT_USER => SOFTWARE => Tobii
— HKEY_LOCAL_MACHINE => SOFTWARE => WOW6432Node => Tobii
– In a normal file browser window’s address bar, type %localappdata% and delete any folders labelled Tobii and TetServer
– In a normal file browser window’s address bar, type %programdata% and delete any folders labelled Tobii and TetServer
– Restart your computer and allow it to install the EyeChip driver again
– Repair all versions of Microsoft Visual C++ Redistributable that you have installed – you can do this from the Programs and Features menu by selecting each one, clicking on Modify and choosing Repair
– Ensure that you have both Microsoft .NET Framework 4.5 and Microsoft Visual C++ Redistributable 2015 packages installed – get these from Microsoft directly if they do not appear in the Programs and Features list
– Download the latest version of the relevant Tobii Core software from http://gaming.tobii.com/getstarted
– Install the software as normal, and check to see if this resolves your issue
Cheers! Hope it works for others too with a similar problem.
