Raspberry Pi OS installation Timed Out

Hello,

I'm trying to install the Matlab and Simulink OS on my Raspberry Pi 3 Model B. I downloaded the support packages from "Get Add-On". When I try to write the OS on the microSD card (4Gb) the process starts, the waiting bar starts to fill, but more or less after 50-60% the installation stops with an alert message "The writing process has timed out".

How can I fix it?

Thanks in advance,

Antonio
