COD dev error 6034 is a bug that’s bothering a number of Call od Duty Warzone and Modern Warfare players. There’s no official word from Activision about it, which means there’s also no proper fix that’s guaranteed to work. However, there are a few things you can try – easy workarounds that might let you enjoy the game until a patch deals with the underlying problem. This guide will list all the things you can do to try to fix COD dev error 6034.
How to fix COD dev error 6034?
If you’re playing on Xbox, the only solution we’ve heard of includes deleting certain add-ons. Go to your games and apps, then select COD and press the menu button. Pick Manage Game and Add-ons, and you’ll see a list. In the list, look for packs called Multiplayer Pack 2 (9.1 GB) and Multiplayer Pack 3 (3.4 GB). Delete them, then restart the console. If this doesn’t help, you can also try deleting the compatibility packs, as well as Special Ops Pack 1, Campaign Pack 1 and Campaign Pack 2.
If you’re on PC, reinstalling the game usually solves it. However, since it’s so big and chunky, you probably don’t want to do it. Thankfully, there’s a way around this as well. Here’s what you should do:
- Open the folder where the game is installed
- Find the following files and delete them: .patch.result, .product, vivoxsdk_x64.dll, Launcher.db, Modern Warfare Launcher.exe
- Run Battle.net and select the game from the list on the left
- Click the options button under the title, then choose scan and repair
- Wait for it to complete, then run the game
This will check the game for any missing files. When it figures which ones you’ve deleted, it’ll redownload only them, but this time, they’ll be the working versions. It’s much better than having to download the entire bajilion gigabytes all over again.
