How to Fix Engine Error Unknown File Version Apex Legends

To fix the Apex Legends Engine Unknown File Version error, there’s a relatively simple set of steps that you can take. First off, right-click on the game in your library, then go to Properties, then Local Files, and click on “Verify integrity of game files.” This is how you do it on Steam, but Origin has a similar system – right-click the game in the library, and then find and click “Repair.” If it doesn’t work, it’s time to widen the scope. This time, delete the file that the error is naming. After that, go through the same set of steps we’ve just described. This should re-download the missing files and the game should work fine from there. Repeat if necessary, as the error sometimes pops back up.

Now, while this system works, it is more of a workaround than a permanent solution. Be sure to log in a complaint with EA’s support. Hopefully, the developers address it in the near future. It keeps appearing with different files every so often, which is a bummer, but at least they try and stomp it out whenever it rears its ugly head.

So, that’s how to fix the Engine Error Unknown File Version Apex Legends bug. If you know of any other method that has worked for you, let us know in the comments. I’ve heard people say that it went away after they’ve changed the language of Origin and reinstalled the game, but I don’t know if that actually works. That might be an even more temporary fix than the one we’ve just laid out.
