Windows recovery involves recovering of system variables (please refer to https://stackoverflow.com/questions/32015759/how-to-recover-deleted-environment-variables just as a starting point), but if you don’t have any further issues (in general for any programs) after our remote session - we recommend to avoid additional interventions.
I really appreciate your help. Yes after our remote session everything works fine. I also recovered the variables i deleted by accident in my trying to install Nuitrack in the first place.
I’m okay now. Thanks again.
