This usually happens if you’re not running BLCMM as an administrator, if the file path to the game’s .exe is wrong, if your antivirus is blocking the tool, or if Borderlands 2 is not installed correctly.
1. Use the Borderlands Hex Multitool
The Borderlands Hex Multitool can fix the “BLCMM Hexedit Executable Error” by automating the hex editing process. This error shows up when BLCMM hasn’t been properly hex edited, or recent game patches have caused issues with automatic hex editing. The Borderlands Hex Multitool is designed to analyze and change the game’s code using hexadecimal values. This tool takes care of the technical parts for you, so BLCMM can work smoothly with Borderlands 2 and any mods you want to use.

4. Exclude BLCMM from Windows Firewall
Adding BLCMM as an exception in Windows Firewall can help fix issues caused by the firewall blocking the tool. Sometimes, the firewall thinks BLCMM is unsafe and blocks its actions. By excluding BLCMM, you allow it to work freely. Note: These steps are for Windows Defender Firewall. If you use a different firewall, the process will be similar but might look a little different.
