At home, I have very bad bandwidth (~1MB/s). I bought a 4G/5G router and have subscribed to a data plan: 260GB/month. It's faster (~10MB/s), but installing games as large as 80GB using the data plan is just not feasible, as it would deplete the available data. So I downloaded the game at a friend's place, on my laptop, using their fiber connection. Yesterday I copied the game from my laptop onto my home computer, into the right folders. But when I start the Heroic Games Launcher, it does not detect the game as installed. I copied both the install directory and the prefixes directory to the right places. Is there anything I missed or I should do to have the game properly detected?
