Hello, I have an Xbox One for which I purchased a physical copy of Halo The Master Chief Collection a few years ago but now I want to install Halo 3 on my PC in another room to play multiplayer over my LAN. I went to my Microsoft account and purchased Halo 3 for $9.99 and told it to install to my PC, it installed the full Master Chief Collection, figured it may have needed to do that and only Halo 3 would be licensed for the PC. Now when I try to start Halo up on both my Xbox and my PC it tells me I can only play the game on one or the other but not both. What do I need to do for it to recognize that I have 2 paid copies of Halo 3? Thanks. QUOTE REPORT EDIT
