Yes, I have even tried installing in Safe Mode. I stopped every service manually in my first attempt after the error and tried uninstalling again. For some reason the USB service always get automatically installed again. I think that your installer has some problems stopping the services to be able to access, modify, replace or delete files. The compatibility between the Eye Experience and the Gaze SDK apps are also suspicious of those issues. A lot of different versions are distributed within the different installer packages (even the standalone drivers installers). Very confusing.
