10. Why can’t I start the custom version of Supremo on my PC where I’m already using Supremo?

To start the custom version on a computer where you are already using Supremo, you have to first disable the option Start Supremo at system boot (unattended access) in the Tools panel.

You then need to close Supremo completely before starting the new custom file (if Supremo is minimised in the bottom bar of Windows, right-click on the icon and select Exit).
