Of course I do, on our servers works a rule - Piracy launchers are restricted, Mojang Launchers are restricted, you can join a server only using our launcher

It generates a unique UUID for an each player

I have rewritten classes of AuthLib on Server and Client side

I understood that this topic is stuck, clothe the thread please

What? It needs mojang authentification for work?

Well, thank you

You don't need to enter Mojang credentials in this launcher, my launcher uses my own auth and registration system. No Mojang and Microsoft services are envolved

What's wrong?

But Vanilla Minecraft works in my launcher

Nothing happens, I took libraries and minecraft.jar with an installed OptifineHD which one properly works in an official launcher

Wait a bit, I'll make that again and send a crash report. At least if it launchs 😃

Here it is

It's my own launcher, you can't know it 😀 With my own structure of clients and versions. Sometimes it crashes, sometimes leaves a lastlog and sometimes does nothing but hangs up in my tasks

The same problem was with OptifineHD

Maybe these two different Forge builds are for injecting them inside minecraft.jar as it was in 1.5.2 and before?

Hi there, I am using Minecraft 1.16.3 with an unofficial launcher and I experience some problems while installing Forge. In an official Minecraft launcher it can be installed using forge installer easily. I tried to copy a JAR file, patched by Forge in an official launcher to my unofficial launcher, and libraries too, but that doesn't work. What's Forge launcher? What's forge universal? What's the difference? And how can they be installed?
