How to fix Dev Error 6034 in Warzone & Modern Warfare
Whilst there is still no official word from Activision about what causes the problem, it’s believed that Dev Error 6034 happens when Modern Warfare files become corrupted or unreadable.
A clean reinstall of the game is known to fix the issue, but there’s a much quicker solution to alleviate the problem. What you have to do is locate specific files in the Modern Warfare folder, delete them, then run a Scan and Repair which will replace the files with the correct versions.
Here’s a guide to the full process:
- Open the Modern Warfare or Warzone installation folder
- Locate and delete the following files: .patch.result, .product, vivoxsdk_x64.dll, Launcher.db, Modern Warfare Launcher.exe
- Now, open Battle.net
- Select the Options’ dropdown
- Then run Scan and Repair on Modern Warfare and/or Warzone
- These deleted files will now be replaced with working ones, and you can play Warzone again.
To prevent this problem from returning, make sure that Warzone downloads are uninterrupted. Leave your PC on until the download is complete, and avoid pausing and resuming the download when possible.
Now hop onto Warzone error free and enjoy the new streaks before Season 3 begins.
