  • Modpacks not launching (Error code '0') / "The System cannot find the file Specified" error (Windows OS) ▾

    If you're trying to launch modpacks but nothing is happening, or the error message "The System cannot find the file Specified" shows up, please try the following solutions:

    • Reinstalling the Launcher
      To reinstall the launcher, open the menu to your right and select 'Repair installation'. Then, try to launch a modpack again.


    • Fixing the Command Prompt (cmd.exe)
      You may experience this issue if CurseForge cannot access the Command Prompt (C:\Windows\System32\cmd.exe) file in your system.
      If the file has been modified, or its name has been changed - please restore it to its original state and try to launch your modpacks again.
      If you can run the Command Prompt but it closes as soon as it starts - that could indicate a corruption due to malware. To fix the corruption, you can follow the steps in this guide, but please note that it should be done very carefully as it requires you to handle your system's registry.
