Hi,
Sorry to bring this up years after, but I just tried to use the sdk with unity 5.3.4f1 on a windows 7 PC and when I try and load the game, it gives me :
EyeX initialization failed because the client access library ‘Tobii.EyeX.Client.dll’ could not be loaded. Please make sure that it is present in the Unity project directory. You can find it in the SDK package, in the lib/x86 directory. (Currently only Windows is supported.)
UnityEngine.Debug:LogError(Object)
EyeXHost:InitializeEyeX() (at Assets/Standard Assets/EyeXFramework/EyeXHost.cs:462)
EyeXHost:Start() (at Assets/Standard Assets/EyeXFramework/EyeXHost.cs:217)
Which even after going through many previous links still wasn’t fixed, even though now the sdk comes with the dll in the plugins folder and so on.
