Fix: BLCMM Hexedit Executable Error

The Borderlands Community Modding Manager (BLCMM) is a popular modding software for Borderlands 2, allowing players to install and customize mod packs for an enhanced gaming experience. However, a recent update introduced a bug known as the “BLCMM Hexedit Executable Error”, causing frustration among seasoned users.

The Hexedit executable error occurs when the BLCMM application hasn’t undergone proper hex editing or when the recent patch reverted the automatic hex editing feature previously present in the software.

This error in Borderlands 2 also can occur when the game encounters compatibility issues or corrupt game files. It can be frustrating to deal with, but fortunately, there are several steps you can take to resolve the issue and continue your gaming adventure.

The error can occur due to the changes in the software’s hex editing process. The developers may have made this change to optimize the software for older or less powerful machines, but the exact reason is unclear. In some cases, the error may occur if the game has not been properly hex edited, or if there are conflicts with other software or antivirus programs.

How can I fix the BLCMM hexedit executable error?

• Use the Borderlands Hex Multitool: This tool can automatically hex edit your files. Ensure you are using the latest version, verify your game files through Steam, temporarily disable antivirus software, and make sure you have .NET Framework 4.5 installed.
• Install Java: BLCMM relies on Java, so make sure you have it installed on your system. Reinstalling Java can often fix any issues related to it.
• Manual Hex Editing: This method involves manually editing specific hex values in the game files. It requires caution and knowledge of hex editing. Detailed steps can be found in the provided guide.
• Exclude BLCMM from Firewall: You can also try excluding the hex editing tool (such as BLCMM or Borderlands Hex Multitool) from your firewall settings. Sometimes, firewalls can block certain functionalities of the tool, leading to errors.

4. Exclude BLCMM from Windows Firewall

Excluding BLCMM from the Windows Firewall helps to fix the error by ensuring that the firewall doesn’t block the communication between BLCMM and the necessary resources. When BLCMM tries to access the internet or communicate with other applications, the firewall may mistakenly identify it as a potential security risk and block its functionality.

By excluding BLCMM from the firewall, you grant it the necessary permissions to operate without interference. To exclude the BLCMM program from the Windows Firewall, follow these steps:

1. Open the Windows Security app by clicking on the Start button and selecting “Settings” (the gear icon).
2. In the Settings window, click on “Update & Security” and then select “Windows Security” from the left-hand menu.

   

3. Click on “Firewall & network protection”.
4. Under “Public Network,” click on “Allow an app through firewall.

   

5. Click on the “Change settings” button. If prompted for administrator permission, confirm it.
6. Scroll through the list of apps and locate “BLCMM” or the specific executable file of BLCMM. If it’s not listed, click on “Allow another app” and browse to select the BLCMM executable file.
7. Once you’ve located BLCMM, check both the “Private” and “Public” checkboxes next to it to allow it through the firewall for both network types.

   

8. Click “OK” to save the changes.

Keep in mind that the steps provided are specifically for Windows Defender Firewall. If you’re using a third-party firewall software, the steps may differ slightly.

To prevent the BLCMM hexedit executable error from happening in the future, you can take the following precautions:

• Keep your Borderlands game and BLCMM application up to date. Install updates and patches released by the developers.
