ERROR: No initial system image for this configuration

[evamoreno]

Hello I´m starting a new project in App Inventor, and installed the AiStarter emulator.
I have Windows 10 Pro, and this message about ERROR: No initial system image for this configuration appears.

Also appears another in spanish language: [WinError 10053] Se ha anulado una conexión establecida por el software en su equipo host

Thank you very much for your help
Kind Regards

Any suggestion?
