How To Fix Exe/Bad_Challenge Error in Modern Warfare 2

Call of Duty: Modern Warfare 2 is off to a great start; however, it is facing a bunch of different errors and bugs that are stopping players from getting a good experience. One of them is the “exe/bad_challenge” error, and it occurs primarily for console players. 

Due to this error, players are sent back to the starting screen of the game, and they are not able to play the game at all. While Activision has not revealed any statement or solution to the “exe/bad_challenge” error, you can try out the methods listed in this guide that might potentially solve this issue.

First of all, restart the game and while you enter matchmaking, go to some other section of Modern Warfare 2 instead of staying in the lobby. It will prevent the error from getting triggered, and once you find the match, you will instantly jump into it. 

If this doesn’t work, turn off your console and restart it, as it will help refresh the system, and you might bypass the “exe/bad_challenge” error. Also, make sure that you have the latest update of the game, as playing on an older version triggers various bugs in online games. 

If none of the above fixes work, you can report it to the Activision support website, and they will come back to you with a possible solution based on the information you provide, or else simply wait for Activision to release a hotfix that will solve this problem for everyone.
