thank you for the reply.
I have full admin rights on this IMac (2017) running on Mojave. It is the first time I use RTI - and I would like to learn how to use it.
Urgently I need to see and process 1 file: https://www.dropbox.com/s/8lnrzr9ewg3wzbx/0342.JPG?dl=0 / https://www.dropbox.com/s/1r9sde1mqm6fflt/0342.jpeg?dl=0
I managed to open the RTI builder, but now I have another error: https://www.dropbox.com/s/knn2qcp4alwv824/Screenshot 2019-08-08 at 06.46.46.png?dl=0
Would it be possible to get this file as RTI somehow?
