1.12.2 forge isn't working?

[Thegeekatron]

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.

[MDW01]

Post Logs.

[Toasty]

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

Additional information

[MDW01]

Very helpful without the logs.

[Toasty]

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

[MDW01]

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

[Toasty]

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]

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]

Your log clearly says Minecraft 1.8 loading

[Toasty]

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

[MDW01]

Then find the right log and post it.

[Toasty]

 You told me to show you this log

Spoiler

fml-client-latest.log

 

[MDW01]

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

[Toasty]

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]

Possibly.

[Toasty]

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]

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.

Post Logs.

 

[Thegeekatron]

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]

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

[MDW01]

You gave me the log for Minecraft Version: 1.7.10

[Thegeekatron]

oh, whoops, sorry.

 

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

[loordgek]

then you are not running 1.12.2

 

for that log you posted you need the AnimationAPI

@Toasty create your own thread

[Thegeekatron]

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.
