Trying to install halo 5

Sounds like you're in the preview. For future reference you should post to the preview forums concerning issues with it.

As for the download, what you're seeing is a known issue. Don't stop it and let it continue until it completes.

So you try to install Halo 1 from the MCC and it stops downloading at a certain percent every time? Are you trying to install on an external HD, or the internal one? I assume you've already tried a power cycle? Also have you tried installing other games
and seeing if they will fully install, or if it is just this one game in particular that will not work?

both on the internal and external drives idk what to do both halo mcc and halo 5 don't want to work for me the rest of the halo games work ( reach, odst ce, etc.) But not halo 5 and mcc both pre owned again

Try doing what Echo4Ent suggests. If that still does. Not work you may need to reach out to the official support line for help.

there is definately an issue there as halo 5 is nearly 100gb so you are missing a huge chunk of data there. easiest way is to put in disc or try installing, when the install gets to 10% cancel and that may fix it.

Hello

The console came with a downloadable code, these are tied to the account that redeemed it and not the console itself. You can't download the game again unless you are the owner of the account that downloaded it.
