The “Oops, It’s Not Working” Troubleshooting Guide

  • Windows: Press Win+R, then type %appdata%.minecraft, then press OK.
  • MacOS: In the Finder, from the top Go menu, select ‘Go to Folder’, then type: ~/Library/Application Support/minecraft, and click Go.
  • Linux: c’mon you’re running linux 🥰

ahahahahah… [pained smile] I’d recommend trying my “Moving to Sodium” retrospective write-up for a good place to start your mod adventure: https://blisschen.co/post/667064183329783808/moving-to-sodium-from-optifine-a-retrospective

  • You may be missing the latest version of Java on your computer, which can be grabbed without Oracle’s restrictions at https://adoptium.net/. Note: you can have multiple versions of Java on your computer!
    • Java 8 is the only version that works for Minecraft 1.15 or lower
    • Java 16+ is required for Minecraft 1.16 to 1.17
    • Java 17+ is required for Minecraft 1.18 and higher
  • If you’re still having trouble or the icon still doesn’t look right, try running Jarfix! (will directly download the .exe at this link, don’t be alarmed!) https://johann.loefflmann.net/downloads/jarfix.exe

As long as you have Optifine installed, those warnings can be safely bypassed and ignored.

Microsoft scare-tactics. Ignore it. If you’re running Windows 10 or later, you’re protected from malicious .jar files via Microsoft Defender.

  • Double-check your Java launch profile is set to the correct version (Optifine or Sodium, not vanilla).
  • Inside the graphics menu, under Quality -> Custom Entity Models, Custom Items, Connected Textures and Natural Textures must be set to fast or fancy, not off.
  • Does your Optifine version have a “_pre” after it? If so, Optifine will not work. Head to Optifine.net and pick up the latest non-developer version.
  • Try restarting your game once or twice. Often issues can be resolved that way.
  • If you’ve still stuck, ask in #troubleshooting at discord.gg/blisschen

If you did everything correct, but the pack isn’t showing up– we need to dive a bit deeper here!

You’ll need to unzip these packs (.zip or .rar files) inside your .minecraft/resourcepacks using 7-Zip, a free archive extraction app. Once installed, right-click the misbehaving .RAR or .ZIP file, hover over 7-Zip in the dropdown, and then click “Extract here” to add a new folder with the resource pack inside. Launch your game again and check if the pack is now there!

CITs are for Java Edition only.

Optifine and Forge/Fabric do not give support for cracked versions of Minecraft and the Chinese-excusive Edition. There are, however, official ports of a handful of CIT packs for Bedrock/PE, which you can take a look at here: blisschen.co/bedrock
