I don’t see a possibility to attach picture, therefore I try to post link for screenshot from VS with aforementioned error: “https://drive.google.com/file/d/1EoUbyPKOnMBElfPA-L5glV86HislOQg_/view?usp=sharing”.
This shot was captured on DebugGameEditor configuration run.
Additionally, before I try to use Tobii UE4 plugin, I’d install a core software from Tobii_Eye_Tracking_Core_v2.16.4.67_x86.
