Summary: First, I inserted the disc, installed and added the serial key when prompted by the game NOT BY GOING TO GAMES FOR WINDOWS LIVE, that could possibly void the game. do not go out of your way to make it work, just follow the on-screen steps your given and you should be fine.
Summary: I love playing Halo. I got a new computer but lost the CD case with the Key. Even though I loaded it to my computer I was not able to get the key so I bought another game. I am disappointed that they are no longer making Halo programs for the the new Windows 8 operating system.
Summary: might just as well buy bioshock 2 with this, will save you a world of trouble getting it to play. First step is to get it loaded.. Install by copying the disk to your hard drive and run set up from there. put your errors on the internet to see what to do next.. and good luck.
Summary: So I have windows 7 and I bought this game because I LOVED the original Halo: Combat Evolved PC game. Bought from amazon, installed it, tried to run it, but kept getting an error message about windows live failing to initialize.
Summary: It okay for achievement. And people like me that a good thing. But the achievement can be glitchey. So try completet a levle in one seting for geting levle achievement. For some reason it will not unlock for stop playing at some point in the levle. And then restart it later and completet the levle.
Summary: It was hard downloading... And once it did, i got some windows live problem. I've looked it up online, and the problem requires me to reinstall the game all over again. I'll do that soon, but I bet this is a good game.
Summary: This game is buggy. Badly buggy. You need to update it before you can play it proper and the update process can be buggy. For example, I got into an update loop that randomly fixed itself when I minimized the game while patching.
