I bought Minecraft for the Xbox one, which in turn gave me the Windows 10 edition for free (still on my Xbox.) Now I want to play on PC for a school project in com tech, but it says I have not purchased it. Does that mean I have to buy the game again or is there a way around this?
Minecraft Java edition (for computers) is a completely separate game from whatever you can buy on consoles.
You have to download it off of the windows store application. Make sure you are logged into the same Microsoft account as the one you bought Minecraft for Xbox.
