Invalid File Selected
BLCMM couldn’t recognize this file.Please make sure you’re selecting a .blcm (mod package) or .txt (mod list) file.
Common mod files for Borderlands 2, TPS, or BL3 use specific headers like#Titleor#ModInfo.Try this:
• Check that the file isn’t empty or corrupted.
• Open it in Notepad — if it doesn’t start with mod syntax, it’s not a valid BLCMM mod file.
• Still stuck? Try re-downloading the mod or exporting it from the mod builder.
Version compatibility is critical. If you are running BLCMM version 1.x and trying to open a mod built with version 2.x (or vice versa), the schema may have changed. The current standard is BLCMM 2.x.
The Fix:
mods folder. Sometimes old config files get reset.BLCMM relies on a specific patch.txt file located in the game's binary directory (e.g., Binaries/Win32). This file injects the mod hooks into the game.
patch.txt from the game Win32 folder.If the issue persists after these steps, it is likely a permission issue. Ensure your Steam Library (and specifically the Borderlands game folder) is not located in Program Files (x86), as Windows User Account Control (UAC) frequently blocks BLCMM from writing the necessary files, resulting in invalid file errors.
To resolve the "Invalid File Selected" error in BLCMM (Borderlands Community Mod Manager) blcmm invalid file selected
, you generally need to ensure the manager is targeting a recognized game path or use an updated tool, as BLCMM is largely outdated. Primary Fixes
Target the Correct File: When BLCMM asks you to select your game executable, ensure you are selecting Borderlands2.exe located in the Binaries\Win32 folder of your game directory.
The "Steam" Substring Requirement: BLCMM often fails to recognize a game path if it does not contain the word "steam".
If your game is installed elsewhere (e.g., a custom folder or Epic Games), create a new folder named steam within your game directory.
Move the game files into this new steam folder and then point BLCMM to the .exe within that path.
Switch to OpenBLCMM: Because the original BLCMM hasn't been updated for recent game patches, many users have switched to OpenBLCMM, which has better compatibility with modern versions of the game. Alternative Tools for Specific Errors
Hex Editing: If you are getting this error while trying to "Setup game files for mods," use the Borderlands Hex Multitool instead. It is more reliable for the initial hex-edit required to enable the console. 🔧 Friendly Error Message (for in-app display)
Epic Games Version: BLCMM natively struggles with the Epic Games Store version. You should use the Hex Multitool to enable mods and only use BLCMM to manage or merge the .txt mod files themselves. Steps for a Successful Report
If you are submitting this as a bug report to a community group or developer, include these details: Game Version: (Steam, Epic Games Store, or other). File Path: Copy the exact path to your Borderlands2.exe.
Action Taken: State exactly what you clicked (e.g., "Tools > Setup game files" or "File > Open").
Java Version: BLCMM requires a specific Java environment to function correctly. Are you using the Steam or Epic Games version of the game?
The "invalid file selected" error in BLCMM (Borderlands Community Mod Manager)
typically occurs when the tool cannot verify the path to your game executable or when trying to use it with versions of the game it doesn't natively recognize (like the Epic Games Store version). Common Fixes for "Invalid File Selected"
The "Steam" Folder Workaround: BLCMM often looks for the word "steam" in the file path to validate it. If your game is installed elsewhere (e.g., a non-Steam folder or the Epic Games Store), creating a folder named steam inside your game directory and moving the game files into it can often trick the manager into accepting the path. a custom folder or Epic Games)
Manual Binary Selection: Ensure you are selecting the actual game executable. For Borderlands 2, this is usually located in:...\Borderlands 2\Binaries\Win32\Borderlands2.exe.
Epic Games Store Compatibility: There is a known issue where BLCMM does not auto-detect the Epic Games version. If the manual selection still fails, users on Reddit suggest using OpenBLCMM, which is a more modern, cross-platform version of the tool that handles different game versions more effectively. Troubleshooting Checklist
Check Permissions: Run BLCMM as an Administrator. It may be failing because it doesn't have permission to "see" or write to the game folders.
Hex Editing: Before BLCMM can properly manage mods, your game's .exe must be "hex edited" to allow console commands. BLCMM has a built-in tool for this, but if it fails, you may need to use the Borderlands Hex Multitool separately.
File Naming: When executing a mod in-game, ensure the filename you save in BLCMM matches exactly (e.g., exec Patch.txt) and is placed in the Binaries folder.
