Unable to launch Halo MCC via Cloud Gaming on PC Xbox app

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.

I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Wagyu

In order to isolate a bit more the issue, please try running the game via xbox.com/play

Let me know if there the game starts as usual.

If yes, may I know which troubleshooting steps you have done so far to fix this?

In that way I can advise you different things or how to proceed.

And are you on Windows 10 or 11?

--------------

In the meantime, try this together:

Open Settings, click Update and Security and then Windows Update;

Click Check for Updates;

Click the Download and Install Now option, if available (Install optional updates as well)

Also, check the Microsoft Store for any updates on the Xbox apps and its services and update everything too.

Now, sign out from your account on both Xbox app and Microsoft Store and do this:

Go to windows settings > apps > search for gaming services app > click on it and select advanced options.

After that, click repair and then reset

Then do the same for the Xbox app:

Go to windows settings > apps > search for Xbox app > click on it and select advanced options.

After that, click repair and then reset

Finally do this:

Step 1: Open the Run window by pressing Windows + R key.

Step 2: Input WSReset.exe in the Run window and click OK.

Step 3: Then a command prompt window will appear. After a few seconds, Windows Store will open.

Sign in again on both Microsoft store and Xbox app with your account and try again

Hi! The issue has been resolved?
Are you able to play as usual?

Halo MCC is NOT play anywhere, if you buy for xbox you can only use it on xbox, if you buy for pc via xbox app you can only use it via pc.

It is cross save only.

Hi Christopher - thank you for the response.

Okay, I've uninstalled the xbox app completely and I then launched MCC from the start menu and the MS Store and all the games are still showing as locked out.

I've tried launching Reach and Halo 4 directly from the installed page on the MS Store but that doesn't seem to trigger anything.

I've tried reinstalling the xbox app and launching halo 4 from there and it's the same problem.

I've tried launching it in the cloud and that does work, all the games are unlocked.

Any ideas?

Thanks

it is because its part of the halo MCC, you need the base part which is halo MCC then the individual games so it reserves space for them, halo 1 on pc for instance is 8.58GB and then add on the MCC base game it becomes 30.08GB.

halo mcc consists of all the games which take 142GB of space on pc so it saves this space aside, when you install hmcc and just one of the games which is also split into multiplayer and campaign it looks like it still reserves the space, this is what i have seen on xbox and gamepass pc, when i install via steam and just choose one of the games to be installed then the space taken is just by mcc and that one game.
