Minecraft forge doesnt work at all (all versions)

Posted October 4, 20205 yr

Sorry for the respost but i tried it on newer versions of mc and still same thing. This is what i said before.
"So its been a while since i played mc and i decide to launch my old mc instance (multiMC) and it errors instantly. Everytime. Used to work just fine. Vanilla launches no problem as soon as i install forge and run i get an error. I reinstalled java 1.8 still same issue. Restarted my computer. No change. Even on the normal mc launcher. Literally no idea what to do now. i've attached the crash report. Thanks for reading." Tried it on 1.16.3 and i got an error. i tried it on 1.14.4 and got an error. i dunno to which version this forum supports mc but ive done it on the newest version now and still same thing.

1.16.3 logs:

That looks like you are using Java 15, which is currently not supported by Forge.

Post the debug.log.

Nah fixed it. Deleting the .Minecraft folded in appdata and reinstalling MC fixed it. Also I was using java 8.

FoxyWoxy In Wemmbus videos the stab shots are with tnt minecarts and not tnt. Yours works ok but I would appreciate that change in the future. Thanks!
