Hi Federico,
I see you have also submitted a Support Request about this so Ill answer fully there.
But for the benefit of anyone reading this post, we no longer support any version of Windows prior to Windows 10. If you are using an earlier version, please update your system to Windows 10 and ensure you are also running the latest version of Immersive Studio.
If your unit also requires a new calibration file, please contact Support to arrange this as the unit will need to be returned to us.
