Modern Warfare & Warzone - How to fix dev error 6036

Dev error 6036 in Call of Duty: Modern Warfare and Warzone is another issue that results in game crashes. The bad news is that this error message doesn’t describe the nature of the problem. Fortunately, there’s a trick you can use to fix code 6036 that involves deleting a few files in the game’s installation folder.

As confirmed by the Call of Duty community, the most common fix for dev error 6036 involves deleting extra files in the Modern Warfare installation folder. Specifically, you need to delete the files in the directory, but not the sub-folders. This forces the game to update itself and download the missing data. Somehow, this solves code 6036.

Here’s how it works:

  1. Head to the Modern Warfare install folder
    1. The default directory is under C:\Program Files (x86)\Activision\
  2. In the Modern Warfare folder, select and delete all the files, making sure to leave the extra folders intact
  3. Once that’s done, launch Modern Warfare or Warzone. The game will issue a warning about a corrupt patch and re-download the data you deleted

It’s not entirely clear why this method works. However, users on the Activision Support forums as well as the Modern Warfare subreddit have confirmed that it fixes the problem. Curiously, this is also the fix suggested for several other non-specific dev error codes.

Since this fix involves deleting and re-downloading data, it’s not something you’ll want to have to repeat. However, if deleting and re-downloading the files fixes the problem, you can safely assume that corrupt data caused the issue. Moving forward, be sure to download and install any future updates without interruption. Doing so should prevent any more data corruption. This advice also applies to users on the Xbox One or PlayStation 4: Let updates download and install without any pausing or delays.
