So I'm trying this Minecraft Modpack I made on Curseforge, but I keep getting "Error Code...

I'm sorry we have no way of supporting your modification attempts.

If you are having the same issue despite using the guide in Josef's Answer:

If you are using a ModPack Launcher such as Curseforge or others, you may not be able to make Minecraft use your GPU despite using the guide, even if you are launching from the Minecraft Launcher.

I uninstalled my ModPack Launcher as I was not using it, and this solved the problem.

For people who want to keep using the ModPack Launcher and resolve the issue, you may have to find Minecraft.exe within the files of that Launcher and do the same thing as in the guide.

Hi, Martin Slovák

Welcome to the Microsoft Community.



It seems like you're experiencing issues with running Minecraft modpacks that use Java 17 on Windows 11. Here are some additional troubleshooting steps you can try:

1. Allocate Sufficient RAM: Make sure you're allocating enough RAM to Minecraft. Sometimes, modpacks require more RAM than the default allocation. You can adjust this in the Minecraft Launcher settings under "Installations" > "More Options" > "JVM Arguments". Try increasing the allocated RAM to see if it helps.
   
2. Check Java Version Compatibility: Ensure that the mods and the Minecraft Forge version you're using are compatible with Java 17. Some mods or Forge versions may not yet fully support Java 17, leading to crashes. You might need to switch to an earlier version of Java (e.g., Java 16) if compatibility issues persist.
   
3. Update Forge: Make sure you're using the latest version of Minecraft Forge compatible with Java 17. Check the Forge website or the CurseForge modpack page for updates. Sometimes, using an outdated version of Forge can cause compatibility issues.
   
4. Update Graphics Drivers: Ensure that your graphics drivers are up to date. Outdated or corrupt graphics drivers can sometimes cause Minecraft to crash. Visit the website of your graphics card manufacturer to download and install the latest drivers.
   
5. Reinstall Minecraft: If none of the above steps work, try uninstalling and reinstalling Minecraft and the CurseForge launcher. This can sometimes fix issues related to corrupted game files or misconfigurations.
   

If you've tried all these steps and are still experiencing issues, you may want to reach out to the Minecraft community forums or the CurseForge support team for further assistance. They may have additional insights or solutions specific to your situation.
