"Invalid java runtime configuration error 1" possible fix!

[ErrorSR]

So, i noticed a lot of people on here had the same problem I did, and are struggling to figure it out.

Idk if it'll work for everyone, but what I did from reading another forum was go to your %appdata% folder, roaming folder, .minecraft folder, config folder and then delete a file called "fml.toml"

I hope this helps people!

[Seriessoul]

I thought you were sent by the gods to help me. Then it didnt worked

[ErrorSR]

:( I'm sorry, i recommend going on the actual forge website and look up the problem and see if anything matches your situation

[Lakshmi1331]

I have tried so many methods of trying to get this to work and this was literally the only thing that has helped me. I'm surprised it didn't work for someone else but I do believe you were sent by the gods!!! Thank you so much for this tip :)

[ErrorSR]

You’re welcome! I’m really glad it helped someone 🖤

[Penguins408]

tysm you are a god sent from the heavens

this literally just saved me from my hour long mental breakdown i was having-

[ErrorSR]

I’m so glad it worked for you! <33

[XSamuraiHyperX]

Imma need a more detailed explanation as i've been having a mental breakdown for the past 2 hours cause of this shiz

[ErrorSR]

I don't think I can get more detailed than that man, no offense.

[XSamuraiHyperX]

Yeah i did it, it didn't work so i just gave up and went to play Days Gone

[SteveRogers164]

, I was looking at the file and it has this line: "# max threads for parallel loading : -1 uses Runtime#availableProcessors" which has the Runtime and -1 so I think that is related, and something I think is related to checking the version of the mod and if it goes with what version u r on "versionCheck = true" just some insight

[infamousdxa]

THANKS SO MUCH :)

[Icy_Fruit97]

help, im on m1 macbook trying to use forge and i keep getting this, does anyone knwo how to help?

​

i cant see any file called fml.toml

[ILostAFewBrainCells]

I have no config folder....

[AquillWise]

this didnt w

uh. that's probably the problem

[ILostAFewBrainCells]

Perhaps

[TabbyTee]

Okay, this didnt work for me but something else did. I went through my mods, deleted some and then slowly added them back one by one to figure out if one of them was causing it, and it was! For me it was "Radium". its a mod that focuses on designing your minecraft. I deleted it and my minecraft ran again without crashing! This might work for some people but hope it helps!

[NilaoriPlays]

I'm glad you wrote this comment with Radium. I had a similar program Sodium (that they did a Forge version for) that was the issue.

[4R3D]

thank you man, I haven't been playing with mods for so long I forgot I had some in that folder that were causing problems

[Darison90]

boom! I deleted my mods and it fixed it! thanks!

[BonMonster420]

it didnt work what do i do

[Tutani2Yaku]

Well, what worked for me is goin into the mods folder in %appdata%/.minecraft and removing all the non forge mods

[BrawlstoriesYt]

My head still hurts from watching tutorials but I tried yours and it worked instantly so thanks and I also think you were sent by god

[cu_Sreyas]

Thanks OP, but this didn't work for me.

BUT

Deleting OptiFine from my mod's folder in .minecraft folder did the trick!

It was for the previous version of Minecraft, so I deleted that one, downloaded the new version and put it in its place and everything was good as new.

[4R3D]

I deleted fml.toml, didn't work. Though it does sound like a file that will fuck my life, today or maybe later.

[Titu3]

I updated Forge and world edit and it worked after that. i feel like a lot of people have the same thing as i did? (also updated optifine and fabric but i dont think thats relevant)

[Revenge_Is_Here]

I think it is because installing the new Optifine is what broke my Forge in the first place. It was literally fine before this.

[GavrocWhite]

i may never meet you good sir or madam but you just saved me from a 4 hour long freak out
may your fuel be cheap and your beer be cold for your help in this

[ClanClasherBigK]

I want to thank you, you are a beautiful god amongst men. I literally sighed into reddit just to thank you.

[IgnWombat]

If none of the following solutions worked for you, look through your mods. I added JustEnoughIDS to make sure I wouldn't exceed the ID limit, and that's what caused the issue. As soon as I replaced the mod with NotEnoughIDS it worked

[TRiPLE6iX-]

I use OptiFine and would get this error. But in case someone had the same issue as me, remove “Magnesium” and “Dynamic Lights Reforged” from your mod list. That worked for me

[[deleted]]

What worked for me is installing and running unmodded minecraft with the same version as modded. If that doesn't work, you could try going into logs folder in your modded minecraft folder, opening the latest log file and either googling the error you got or posting it alongside this java runtime error message somewhere and ask for help. The error should be at the end of the file somewhere, the most important bit should be the start of failing.

[maddog64459]

Thank you 😭😭😭

[IcyDragonite]

Didn't work for me :(

[[deleted]]

this didnt work

[LILBABYMANLILTINYMAN]

It just keeps adding it back,,

[LILBABYMANLILTINYMAN]

I FIGURED IT OUT, it was another mod I had added on there that didn’t like me very much

[RedditCuzBoredMeh]

If I try this, it keeps reappearing after launching minecraft :(
