1.12.2 forge isn't working?

Thegeekatron · May 9, 2018

So I just installed minecraft forge for 1.12.2 yesterday and been trying to work, but each time I try to play it it either stops the launcher from responding or says the game crashed.

I have tried deleting and then reinstalling multiple times.

I'm on Windows by the way.

Post Logs.

Toasty · May 9, 2018

Yeah same here. I did everything I was supposed to do. Install Java, install forge and open minecraft. I opened minecraft using the forge profile. Whenever I click play, it just closes the launcher and never opens up the game itself. I tried leaving the launcher open to see what would happen and it just gives me a crash notice

Very helpful without the logs.

Toasty · May 9, 2018

I don't know how to post logs. I tried reading the instructions and it was confusing for me to keep up with

MDW01 · May 9, 2018

If you are confused by the instructions of where the logs are are you sure you installed forge correctly because all you have to do is upload the logs/fml-{client/server}-latest.log which is found in your .minecraft folder

Could this be it?

You installed Optifine for 1.8.9 on Minecraft 1.8. What made you think that was a good idea? Also, stop using 1.8 its old.

Toasty · May 9, 2018

But I'm not using 1.8... I'm using 1.12.2 that's why I'm on this thread on the first place

MDW01 · May 9, 2018

Your log clearly says Minecraft 1.8 loading

Toasty · May 9, 2018

Maybe I pulled up the wrong one, but trust me, I have no reason to be on 1.8

MDW01 · May 9, 2018

Then find the right log and post it.

Toasty · May 9, 2018

You told me to show you this log

Spoiler

fml-client-latest.log

MDW01 · May 9, 2018

delete all the logs and launch the game and then post it.

Toasty · May 9, 2018

Forge is working now I think. The reason why you saw minecraft 1.8 is because for some reason optifine 1.8.9 was in the mod folder for some reason?

MDW01 · May 9, 2018

Possibly.

Toasty · May 9, 2018

Yep it worked. It's all good now. Thanks for the help, if you haven't pointed out the fact about something having to do with version 1.8, I would've never figured it out

MDW01 · May 9, 2018

No Problem.

So I just installed minecraft forge for 1.12.2 yesterday and been trying to work, but each time I try to play it it either stops the launcher from responding or says the game crashed.

I have tried deleting and then reinstalling multiple times.

I'm on Windows by the way.

...Back to the OP's post

Post Logs.

Thegeekatron · May 9, 2018

huh, the folders empty and now when I try to launch it it just makes the game think it's running even though it isn't.

Thegeekatron · May 9, 2018

wait, I was in the wrong folder, here's the newest one "

You gave me the log for Minecraft Version: 1.7.10

Thegeekatron · May 9, 2018

oh, whoops, sorry.

um... there's no log here for 1.12.2.

loordgek · May 9, 2018

then you are not running 1.12.2

for that log you posted you need the AnimationAPI

@Toasty create your own thread

Thegeekatron · May 9, 2018

no, but I am running 1.12.2, and I figured out how to fix 1.7.10

those were dated the sixth but this started on the seventh, it's just not showing the logs.

1.12.2 forge isn't working?
