It was pretty swift and easy on my Windows 11 OS 64-bit version. My download speed is around 200 Mbps and it took around 15-20 minutes to fully syncronize.
It seems like it'll take me around 6-7 hours if my WiFi speed is 10Mbps. It could even take longer because other family members are using the same network. Perhaps I shall reinstall Utopia on my PC at another time, as I am still curious about this raffle.
Thanks for the info you gave, and good luck with the number you chose!
