What should happen:

Create instance, install forge, click launch, start minecraft

Steps to reproduce the issue (Add more if needed):

  1. Create a new instance (1.12.2)

  2. Install the latest version of Forge

  3. Click Launch

  4. Console gives error

Suspected cause:

It may have been the regular launcher cause when I tried to launch it over there it was stuck on "Preparing", I had no idea how to fix that

That sounds like a network problem, not a software problem. Make sure the network you are using isn't blocking minecraft-related servers and services.

See this reply from peterix, this is probably a network problem.

seanawesome commented 3 years ago

Nevermind, it's only blocking "https://libraries.minecraft.net/com/mojang/minecraft/1.15.2-Impact_4.9.1/minecraft-1.15.2-Impact_4.9.1-client.jar" I don't know how to fix that though

AverageComet250 commented 3 years ago

That's a broken JSON. Why would mojang be hosting files for impact, which is a hacked client (and in all honesty a very good one for anarchy servers). Try creating a new instance using the impact launcher.

kb-1000 commented 3 years ago

This is not the support for Impact. This issue is closed. And @seanawesome you're necromancing old threads.

This is not a network issue as I was able to manually download the files from the listed links.

AverageComet250 commented 1 year ago

Don't think that's a MultiMc issue... also you're necroing this thread again. Either open a new issue on the correct bug tracker or open a new issue on this tracker with more info.

bekosun commented 2 months ago

that was so useless... its a software problem I've disabled firewall I give the software all the necessary permission and still nothing.. I can manually download libraries but the software can't I tried all the workarounds that I can found and nothing works..

phit commented 2 months ago

post your multimc-0.log from the launcher folder, that should give you the reason
