In some cases Windows can associate a driver with the eye tracker when it is connected to a computer without pre-installed drivers.
We therefore recommend to install the software first, to be sure that our driver will be used.
If the eye tracker is associated with the wrong driver.
1) Open the device manager
2) Right click the device(s) that represent the eye tracker and chose 'Uninstall'
3) Reinstall the Gaze Interaction Software and PC-Eye Configuration Guide, that installation contains the correct driver.
It might be possible that a reinstall of the Gaze Interaction Software suffices in some cases.
