By Answering it, I'm removing you from the list because you shouldn't "crack" or "hack" games, and on top of that it's Halo : CE . Which is Combat Evolved.
Please inform yourself and stop attempting to be a cheat. Thank you.
you have to have halo: combat evolved for the PC first.

Well, Halo Custom Edition is the multiplayer version of Halo Combat Evolved PC. It doesn't have a Campaign, by the way. If you want to get Halo Custom Edition, install the installer and use your Halo Combat Evolved PC Key. The main advantage of Halo Custom Edition is custom maps. Halo Custom Edition is currently in Version 1.0.9.620
MAPS
Halo Custom Edition is FREE.You can download Halo CE from http://hce.halomaps.orgTo install Halo CE you need the original Halo Combat Evolved game.
Have you pirated the game? If you have, it won't install. If it's a legitimate copy, make sure it's installed in the "Microsoft Games" Directory.
I would assume you install it.
Yes, there is a halo custom edition.
You install it then play it from the shortcut.
I think you should ask why was halo custom edition created because the reason people download the maps is because they can have fun on halo with other people across the world. halo custom edition was created for that purpose and it only plays maps that you download not the normall halo. your asking why do you it is more like your asking why do I.
DOWNLOAD IT ON FILEFRONT
You can download a demo version of Halo: Combat Evolved for free on the internet. There is also the Halo: Custom Edition, but this requires the CD Key of the full version of Halo: Combat Evolved installed on the computer you install Custom Edition on. Custom Edition is free, and allows for the use of user-created maps. It does not include the campaign though.
Try reinstalling Halo Custom Edition, and make sure you have the latest update. I believe the latest is 1.08. Check Bungie.net for it, I'm sure you'll find it.
Without hacking, I don't think you can. Halo Custom Edition is only PC
