Yeah, that was my first usage of a new version of ue4... So I didn't change anything prior of the Jam, and suddenly, I had 20min left to pack ans send the file... I hit the package button without any configuration.
On nearly 60 games I tested on this Jam, there was only 2 games made in ue...
You're the first to tell me about install prompt and firewall problem... That's weird, there's no net code... I'll check that.
Thanks for you're Review!
