Java is required to run Minecraft modpacks. If you don't have Java installed on your system, you will likely receive the following Windows system message when trying to launch modpacks:

1. Download the latest Java version available here: https://java.com/download (your operating system should be automatically detected, or you can choose it manually here: https://www.java.com/en/download/manual.jsp).
   
   
   
2. Run the installation:
   
   

   
   *Please note that Java will be installed by default inside the system's Program Files directory. If you are not a Windows admin user, you may not have a permission to continue the installation, and you will need to ask a system admin to assist you with the installation:

3. Restart the CurseForge app and try to launch your modpack(s) again.

You can fix this using the 'Repair Installation' button - Please read more about this solution.

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) ▾

  
  

  
  

  If the error "CMD configuration may be causing issues" shows up, it means that CurseForge cannot access the Command Prompt file (C:\Windows\System32\cmd.exe) 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.
  
  

If you've come across an error where trying to set a modding folder, please make sure you did not select a path that is invalid, for example:

• The desktop or a folder within the desktop
• A OneDrive folder, or any folder within the OneDrive directory
• The Vanilla Minecraft directory (C:\Users\[user]\AppData\Roaming\.minecraft\)
• A path that contains non-English letters
• A root folder (C:\, D:\, etc.), as in - the first or top-most directory in a hierarchy

If you're not sure which directory to select, we recommend keeping the default path suggested by the app - C:\Users\[user]\curseforge\, or creating a new folder outside of the C:\Users directory, like C:\CurseForge or D:\CurseForge and selecting that.

If you received an error when trying to import a modpack, please make sure that the modpack's ZIP file is valid and properly structured. The ZIP must contain a manifest.json file inside it.

2. If the modpack uses the Forge modloader, try the solutions suggested here: Issues Related to the Forge Modloader

If you aren't sure about the validity of the ZIP file, or the solutions above have not helped, please reach out the creator of the modpack or send the file to us, and we will do our best to help.
