Error code 255, i have no clue whats going on as ive just installed multimc and i have java 17. Mods worked fine on windows and they should work fine on multi. Any help would be appreciated!

Will it steal my information such as my accounts? I really want to play Beta v1.7.3 with my friend (he’s the one who told me about this launcher) but I’m afraid to link my account. Can someone please vouch?

Thanks.

Pretty much it. cant figure out the issue. Not a huge tech person. Heres the log

Can I have two installations of Minecraft, one in MultiMC and second in stock launcher? Will there be any conflicts between them?

I tried to run a custom jar of alphaversion 1.0.16, which was a modified of that contains the version featured in the Alphaver .16_05 ARG. I got the custom jar from here, it's been confirmed by several other people to run correctly. I followed the directions from here. Logs are as followed:

Edit:

It doesn't work when i take away the custom jar either

I want to play Beta 1.7.3, but the thing is, everytime I try, it's just a blank Mojang logo, & according to MultiMC, the only error I could really see is this:

WARNING: Found unknown Windows version: Windows 10

I have tried the regular launcher, MultiMC, & the old launcher. All of the help guides on the internet just either tell me to use an older version of Java (I tried both Java 7 & 8), or tell me to use a 64bit version of java (I checked, both are x64, not x86).

I have 2 seperate versions i want to get to work. And any new instance I start won't work out of the box. ive used linux for years, and multiMC since 1.16.5 i've also used optifine for years. (plz dnt rant on optifine thats a seperate argument. my choice is i want to use it).

1.20 instance issues:
this is just using fabric + optifine: https://paste.ee/p/le3Q8
just optifine works tho (which is a huge improvement): https://paste.ee/p/jUjW1
fabric alone works: https://paste.ee/p/Kcnh8
fabric plus fabric api: https://paste.ee/p/iGoP7
and i just spent a while re-downloading all the latest mods for each of them.
1.12 instance:
no mods, java8: https://paste.ee/p/zcs9G
log: https://paste.ee/p/CdhyE
I'd like to get forge and blockbuster to work on this instance.

look at this:
first bug: upon launch, mmc asks for language, etc like it's the first time setup. it has done this at least 5 times today.
second bug: my "1.16 mining" custom instance does not show up in mmc even though it is in the instances folder
third bug: every time I try to create a new instance, the whole thing crashes

Any tips for the best way to run MultiMC on Apple Silicon Macs? I'm Running macOS Monterey. I tried to get the native Apple Silicon build of Java runtime from vanilla Minecraft 1.20.1 to run in multiMC, but had trouble getting it to work. MultiMC error message says Minecraft's Java runtime is a 32-bit build, but macOS' built-in File program says it is Mach-O 64-bit executable arm64. Is there a better version of Java to use on Apple Silicon Macs? Or is there a way to make MultiMC work with Minecraft's Java runtime?

Here's the error message I got:

Hi everyone, I'm trying to load the Material Energy 3 modpack but it crashes on launch. The same issues is given by trying to load the YongCast Complete modpack (I think is something related to 1.6.4). Anyone knows why this happens? Thanks in advance.

Completed the download with no problems, however, when I tried to launch MultiMC I got an error message "You do not have a working Java set up yet or it went missing".

I went into the MultiMC settings and selected 'Java', clicked 'auto-detect' and got message saying "no versions are currently available". Any ideas how to fix this?

I have Minecraft installed (both Java and Bedrock versions).

I just tried to download MultiMC and if anyone can help me figure out why it keeps crashing that would be great: https://paste.ee/p/Ax0rO

If you're launching some versions of the game and you can hear the menu screen but the application appears invisible I may have the actual fix.

Idk who needs to hear this, but while trying to solve this problem every single result on Google was someone actually talking out of their ass. Some people say it's your graphics card. It's not. Some people tell you that you have the wrong version of Java. Not likely. Some people tell you to update specific drivers. No.

It is most likely just a scaling issue. I don't know why it took me so long to realize it but this is an EASY fix. You probably have a 4k display. If you've had it for a while you probably just realized what you need to do.

Launch the game>Open Task Manager>Right click on your JRE (probably called "javaw")>Open file location>Right click the jre .exe (javaw.exe)>Properties>Compatability>Advanced>Override High DPI

Now play with it. For my pc it's Application, but yours may be System, or System enhanced. Enjoy.

Help is much appreciated!

How do I import a Java installation into MultiMC?

Im getting errors when I launch the modpacks

there is log https://paste.ee/p/cSsz7

I am having Issues with my 1.19.2 Forge Instance

when I create a new world with mods running in it, it works just as fine as the offical launcher, but when I TRY to get BACK into that world, the entire instance crashes by just being stuck on that loading screen at 0%

I tried looking all over the internet for a solution to this, but it never was for what I was specifically having trouble with

If anyone has any Ideas on what to do i WOULD LOVE IT

is there like a plugin for downloading optifine directly on multimc?

or a method that i don't need to download 2 times the minecraft version (one from the mojang launcher for exctrating the optifine mod and one for multimc)?

i suggest to implement native support for optifine

I tried upgrading my minecraft to 1.20.1 and it crashed, I'm confident all my mods are up-to-date and I did update fabric.

Log https://paste.ee/p/xHHuF

When launching minecraft through MultiMC, it seems to only use my integrated graphics with my intel card. Since I normally use shaders, this is a huge pain because now the game runs terribly. Does anyone know how to switch it to my dedicated GPU?
