Why Can’t I Purchase Modern Warfare Remastered?

With a development team releasing new information every few days, you might be shocked that it takes a month to update some issues in Call of Duty: Modern warfare dev error 6034 Xbox one Remastered.

Modern warfare dev error 6034 Xbox one is causing an issue for many people trying to purchase Call of Duty. Most people aren’t having much luck with Microsoft support or even calling Sledgehammer games directly, so let’s fix dev error 6034 Xbox one today!

1.  Power cycle your console.

To reboot your Xbox One and turn it off, press and hold down your controller’s power button.

Hold down until you see a pop-up indicating that your console is rebooting.

If that doesn’t work, try re-syncing your controllers by following these steps:

  • First, make sure you’re plugged into an outlet or connect via Ethernet cable.
  • Navigate to Settings>Kinect & devices>Bluetooth settings, then turn it on if necessary (and not already).
  • From there, go back to Settings>Devices>Connected devices, then find and select your controller(s) from the list.

2.  Verify the game cache

If you’re trying to play a game and keep getting dev error 6034 Xbox one, start by verifying your game cache.

If that doesn’t work, move on to some of these other potential fixes for dev error 6034 Xbox one.

This process can take a little time, so set aside at least 30 minutes for it, just in case. (You’ll likely need an internet connection, and Microsoft’s gaming software will need to be installed.)

These are the ways to verify your game cache:

From within your console or from a computer. If you choose to do it on your console, follow these steps

  • Press Home.
  • Scroll right to My games & apps > Games > Right-click Call of Duty: Advanced Warfare > [select Manage Game].
  • Select Download all missing files.
  • On your computer, go into Settings > System > Storage and check how much storage space is being used up by each app/game on your Xbox One.
  • Identify which ones are high in use and run them through Download all missing files again (if possible).

You may have to wait a while for updates; if necessary, unplug your console and let it sit overnight or until there’s been enough time for everything to finish downloading.

Then see if you still get dev error 6034 Xbox one when you try again later.

3.  Update your console

If you get an error message while playing a game, try updating your console and verifying the game cache. If there’s a software update available for your console, you can download it directly from Home.

If that doesn’t fix it, go on to this step.

(Note: Restarting won’t delete any of your saved games or settings.)

  • To restart, hold down both triggers for ten seconds until you see an orange light appear above your controller.
  • This restarts your system without turning off or unplugging anything.

So, don’t worry about losing any work or progress!

4.  Reboot your router

Sometimes, an easy fix is as simple as rebooting your router. If you’re on a PC or laptop, try turning it off and back on again.

If that doesn’t work for you, try swapping your ethernet cable for another one. It could be faulty and prevent proper connections between your console and router.

Another potential solution that’s worked in some cases is your console’s hard resetting (or soft resetting).

  • Hold down the power button just for 10 seconds.
  • Then restart it after releasing it.
  • Find Settings>All Settings>Power & startup>Power options >Restart now in case of an emergency.

5.  Contact Activision Support
