You'll have to correct this problem manually.
You need to either add the files, or removed the packages that require them. Instance update failed because: Some artifacts marked as 'local' are missing their files:Ĭ:/Users/jsa09/OneDrive/Desktop/MultiMC/instances/1.14/libraries/OptiFine_1.14_HD_U_F1_pre6 Downloaded the newest version of Optifine and extracted it, so I have the mod file. It should open a window with a list of Java versions. Go to Settings, then make sure the 'Java Installation' checkbox is checked. Java is version 1.8.0_211, using 64-bit architecture. So, I created a new MultiMC instance for 1.18. Create a new Minecraft instance in MultiMC (or duplicate an existing one), then click 'Edit Instance' in the sidebar. Steps to reproduce the issue (Add more if needed):Ĭ:/Users/jsa09/OneDrive/Desktop/MultiMC/instances/1.14/.minecraftĬ:/Program Files (x86)/Common Files/Oracle/Java/javapath/javaw.exe json file looks good and my file is in libraries. When following the steps of the manual optifine install, my game crashes on launch.
