How to Fix Modern Warfare 3 Error 12502

Address Outdated Game Files

Automatic Updates: Most launchers (Steam, Battle.net) automatically check for updates. Launch your launcher and navigate to the update section for Modern Warfare 3. If an update is available, download and install it. This is often the quickest fix, as updates frequently address compatibility issues and bugs that might be causing the Dev Error.
Manual Updates: If automatic updates are disabled, check the launcher's settings to enable them. Alternatively, some launchers might require a manual update check. Look for prompts or options within the launcher itself.

Optimize System Paging File (PC Only)

Virtual Memory Management: The paging file acts as an extension of your RAM. When RAM fills up, data is temporarily stored in the paging file on your hard drive. Adjusting the paging file size can sometimes resolve Dev Errors.
Accessing Settings: Press Windows Key + R to open the Run dialog. Type "sysdm.cpl" and press Enter to open System Properties. Navigate to "Advanced System Settings" and then "Performance Settings". Click "Modify" under Virtual Memory.
Customizing Paging File: Select "Custom size" and set a new paging file size. A general rule of thumb is to allocate paging file size equal to the amount of your RAM or slightly larger. Apply the changes and restart your computer.

Disable Disruptive Overlays

Overlay Conflicts: Some game overlays from programs like Nvidia GeForce Experience, Discord, Steam, Xbox Game Bar (Windows 10/11), or AMD Radeon Software can occasionally interfere with games. While less common, disabling these overlays might help in some Dev Error cases.
Temporary Disabling: Try turning off overlays one by one to see if it resolves the issue. You can usually disable them through the settings menus of these respective programs. Remember to re-enable them after testing if the Dev Error is fixed.

Verify Game File Integrity (PC Only)

Corrupted Files: Damaged game files can also trigger Dev Errors. Steam and some other launchers offer a feature to verify the integrity of game files. This process scans for any corrupted files and redownloads them if necessary. Refer to your launcher's specific instructions on how to perform this verification.

Reinstall the Game (Last Resort):

Fresh Start: If none of the above solutions work, consider reinstalling Modern Warfare 3 as a last resort. This will ensure all game files are clean and up-to-date. Remember to back up any saves you want to keep before reinstalling.
