I cant add games to my horizon!

ples help me every time i drag any thing like dlc and profiles it wont work !!

Does it show this icon?

If so, try running Horizon as an Administrator if you aren’t currently. Or not if you are.

i am runing it in admin mode

it comes up in package manger but i cant modify it or any thing

DLC cannot be edited in the package manager because it’ll break the signature and the Xbox will see the file as corrupt.

it all ready see its corrupted

It sounds like the dlc/game isnt DRM free and you don’t have a licence for the dlc/game so the xbox shows it as corrupt.
