Will Not Download

hello I am trying to install halo 5 on my xbox and it will only go to 7% I have exchange my halo copy and it still does the same thing I have contacted xbox and they said it is not my console or my internet and it is not the disk it will go to 7% one time 8% next or 20% the highest I have gotten it to is 58% and I’m getting tired of trying to install the game. I need this fix if. I have tried to contact someone on here to help me no message back.

I have a similar problem, but I can never get past 0%.

By any chance are you running the New Xbox One Experience preview?
