Could you already install your EyeX, what I did and worked was to extract all the contents from Tobii.Eye.Experience_0.8.17.1196-alpha.exe using winrar; and individually run the MSI files that are located in /InstallationGuide/CoreComponents. Doing this I was able to install EyeX_0.8.17.1196-alpha correctly. I hope this works for you too
Note, I got a warning that a key couldn’t be writen in the register, just ignore it (twice).
Jenny, Can we know which keys are these ones in order to add them manually?
I’m using W8.1, with all the system requirements
