I understand Roberts VII is available for PC, distributed on a CD. Can you install it on your PC from the CD, or do you always have to work via a CD drive?
I have checked the official website and I have seen that the software allows customization which means the settings are saved somewhere, therefore it requires installation. When you insert the CD, a setup procedure will start then when it's finished, you will have the possibility of launching the application from your computer, but the CD might be required to be in the tray for verification purposes.
