Thank you for quick reply.
My PC do not have ‘HKEY_LOCAL_MACHINE\SOFTWARE\\Tobii\\TobiiUpdater’
Instead, there is a key ‘HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Tobii\TobiiUpdater’
Under this key, there are several keys and values such as
EyeXConfig, EyeXInteraction,..,TobiiService.
I exported this section of the registry and remove \Wow6432Node and import it.
Now, the software seems to work well. I don’t have Tobii eyeX on hand now and I’ll test tomorrow.
Thank you for the information.
