How to fix the EXE/Bad Challenge error in Modern Warfare 2

Another problem known as "exe/bad challenge" has been detected in Call of Duty: Modern Warfare 2, which renders the game unplayable. 

Here is how to fix the EXE/Bad Challenge error in Modern Warfare 2. The recently released Call of Duty: Modern Warfare 2 is driving players insane everywhere. The first-person shooter is renowned for its cutting-edge graphics and action, but it’s beginning to develop a reputation for something Activision may not be a big fan of.

In the days and weeks after the release, several issues have surfaced. Accidental wall-hacking, crashing, and other bugs have appeared as glitches that want to compete.

The “EXE/BAD CHALLENGE” bug is present and eager to draw attention to itself. Players from all around the world are affected.

What is the “EXE/BAD_CHALLENGE” bug and how do you fix it?

After giving supporters extra tokens for experience points and weapon experience points as a result of glitches, the problem started to manifest. Sadly, their attempt to make things better only made things worse.

The following are the best methods for fixing the “EXE/BAD CHALLENGE” bug:

Check for game updates

Players must first tap the MW2 icon on the home screen, then “settings,” and finally “check for updates,” to do this.

For PC users, open the “” client and select “check for updates” from the cog next to the game’s name on the bottom left.

Choose “manage” for Xbox users, then go to “updates.”

Avoid sitting around the lobby

The majority of incidents have been brought on by waiting in the lobby. Just make sure you’re looking for games or leaving the lobby if you’re not. If not, you’ll probably run across this issue.

Restart the game

On a console or computer, you can restart your game. Restart the game first, of course. Try rebooting your entire device to see if the problem still exists.

Call of Duty: Modern Warfare 2 installation again

Reinstalling the game is the final piece of advice. The problem can be resolved by reinstalling Modern Warfare 2, but there is no assurance as to how long that fix will last.

These ought should solve the problem. Activision will hopefully fix any bugs so we can resume popping heads and hiding in corners.
