What Is the “Join Failed Because You Are On a Different Version” Error in MW2?

The “Join failed because you are on a different version” issue in Modern Warfare 2 appears when you are trying to play with another user and one of your games is not updated to the latest version.

You won’t be able to play online without a fully updated copy of MW2 because it’s essentially like trying to play two entirely different games together.

The game treats the updated copy and the not updated copy as two separate versions, hence the “different version” part of the issue.
