HALO MCC Will not launch - says app is offline

Daemonpryde · Jul 21, 2020

I have been struggling for 3 days now. I have managed to get MCC to launch once, for 10 minutes. Every time I try to launch it, it tells me the app is offline... my internet is fine, I'm signed in to my Xbox account, and there's nothing wrong with my PC.
What the Hell?

I'm having a similar issue. When prompted in, say, Destiny or Halo MCC to hold down the X-button, sometimes I'm abruptly taken to the dashboard or another app (like Upload) is launched. Naturally, that can be very annoying during gameplay, whether online
or offline. What could be causing the issue?

Just tested, my child was able to launch (from steam), login, and play two matches of Halo Infinite without any hinderances.

I then downloaded the XBgaming app, and ensured that her content settings were allowed to go up to 18+ (Halo MCC is rated M), and still no luck. same message about 3rd party apps being blocked. I noticed on the app it stated exceptions for apps to be allowed (we have Spoitfy, XBox Beta, Minecraft for example). Is there a way to allow Halo MCC to be an exception then?

I have the same problem!! I have bought this game and click the MCC, it launches, I see the "easy anti-cheat" window load, then the opening cinematic plays, it then closes or crashes when the "343 industries" shows
and the Halo Reach Microsoft app page is opened and says I need to install Halo Reach. But I did install it!!!!!

Halo MCC. What a disaster of a launch. As a long time Halo fan it was a real let down.
