west coyote Dec 22, 2022, 10:57 PM

#

west crow Dec 22, 2022, 10:57 PM

#

edit your environment variables

#

west coyote Dec 22, 2022, 10:58 PM

#

umm one sec lemme pull up

#

noop

#

west crow Dec 22, 2022, 11:15 PM

#

west coyote Dec 22, 2022, 11:16 PM

#

west crow Dec 22, 2022, 11:17 PM

#

what's the output of set in cmd?

west coyote Dec 22, 2022, 11:17 PM

#

west crow Dec 22, 2022, 11:17 PM

#

does it contain java specific stuff?

west crow Dec 22, 2022, 11:17 PM

#

west coyote just set?

yes

west coyote Dec 22, 2022, 11:18 PM

#

west crow Dec 22, 2022, 11:18 PM

#

it should show all resolved environment variables

west coyote Dec 22, 2022, 11:19 PM

#

this is the only thing i see?

#

related to java*

west crow Dec 22, 2022, 11:20 PM

#

but java -version shows that weird output?

west coyote Dec 22, 2022, 11:20 PM

#

yeah

#

west crow Dec 22, 2022, 11:20 PM

#

and nothing with tool options or arguments in the output of set?

#

and nothing similar to Xmx512M?

west coyote Dec 22, 2022, 11:21 PM

#

just the thing with the weird u in front of it

west crow Dec 22, 2022, 11:21 PM

#

Did you recently attemt to change how much memory (RAM) is given to Minecraft?

west crow Dec 22, 2022, 11:21 PM

#

west coyote just the thing with the weird u in front of it

in the output of set?

west coyote Dec 22, 2022, 11:22 PM

#

west crow in the output of `set`?

no, in the java -version

west coyote Dec 22, 2022, 11:22 PM

#

west crow Did you recently attemt to change how much memory (RAM) is given to Minecraft?

yeah, but that was in one of the attempts to fix this issue

west crow Dec 22, 2022, 11:22 PM

#

west coyote yeah, but that was in one of the attempts to fix this issue

How did you do that?

west coyote Dec 22, 2022, 11:22 PM

#

environmental variables i believe

west crow Dec 22, 2022, 11:22 PM

#

which ones?

west coyote Dec 22, 2022, 11:23 PM

#

west crow Dec 22, 2022, 11:23 PM

#

oh yeah

#

remove that one

west coyote Dec 22, 2022, 11:23 PM

#

remove completely?

west crow Dec 22, 2022, 11:23 PM

#

or replace the - at the beginning

#

it's the wrong dash symbol

#

it should be -

west coyote Dec 22, 2022, 11:23 PM

#

oh dear

#

west crow Dec 22, 2022, 11:24 PM

#

or completely remove the environment variable

west coyote Dec 22, 2022, 11:24 PM

#

alrighty, i changed it

#

i'll try removing it if it still doesn't work

west crow Dec 22, 2022, 11:24 PM

#

oh and you might need to restart to apply the changes

#

like first click ok in the environment variables thing

west coyote Dec 22, 2022, 11:25 PM

#

so is this. normal now?

west crow Dec 22, 2022, 11:25 PM

#

then restart cmd and the Minecraft launcher

west crow Dec 22, 2022, 11:25 PM

#

west coyote so is this. normal now?

yes

west coyote Dec 22, 2022, 11:26 PM

#

alright, i got the error again but im gonna assume it's cause i didn't restart

#

so i'll try that first

#

i'm still getting this when i try to launch minecraft :(

west crow Dec 22, 2022, 11:28 PM

#

did you completely close Minecraft launcher etx before that?

west coyote Dec 22, 2022, 11:29 PM

#

yeah, i closed through task manager

west crow Dec 22, 2022, 11:29 PM

#

then you reopened Minecraft launcher and then Minecraft?

west coyote Dec 22, 2022, 11:30 PM

#

didn't get to open minecraft, i opened the launcher, clicked play, and then got that message after a few seconds of loading

west crow Dec 22, 2022, 11:31 PM

#

does Minecraft launcher allow you to configure jvm args etc?

#

or java options or something with java runtime?

#

or arguments

west coyote Dec 22, 2022, 11:32 PM

#

?

west crow Dec 22, 2022, 11:33 PM

#

in java executable

#

is there javaw.exe at the end?

west coyote Dec 22, 2022, 11:33 PM

#

yessir

west crow Dec 22, 2022, 11:33 PM

#

remove the w so it ends with java.exe

#

does that change anything?

west coyote Dec 22, 2022, 11:34 PM

#

now it gives me this error instead

west crow Dec 22, 2022, 11:35 PM

#

hm

west coyote Dec 22, 2022, 11:35 PM

#

(i also wanna say i really appreciate you helping me out, i am just a silly little guy who wants to mine the craft)

west crow Dec 22, 2022, 11:35 PM

#

did you ever touch the java executable thing?

west coyote Dec 22, 2022, 11:36 PM

#

west coyote ?

this one?

#

yeah, changed it to java.exe

west crow Dec 22, 2022, 11:36 PM

#

I meant earlier

west coyote Dec 22, 2022, 11:36 PM

#

oh! nope

#

i changed it to javaw.exe cause a friend suggested, but both versions give the same error

west crow Dec 22, 2022, 11:37 PM

#

go back to javaw.exe

#

then take the whole stuff with jvm arguments

#

copy it somewhere so you have a backup of the text

#

then remove the entire line under jvm arguments

west coyote Dec 22, 2022, 11:38 PM

#

same error :(

#

west crow Dec 22, 2022, 11:39 PM

#

the java executable

#

did you convert it back to javaw.exe?

west coyote Dec 22, 2022, 11:40 PM

#

yep!

#

try it again with java.exe?

west crow Dec 22, 2022, 11:40 PM

#

so with the jvm arguments removed, you are getting the white error box

#

and without it, you are getting the launching the game failed error?

west coyote Dec 22, 2022, 11:41 PM

#

with and without the arguments removed, i get the launching the game failed error

west crow Dec 22, 2022, 11:41 PM

#

ok

west coyote Dec 22, 2022, 11:42 PM

#

ignore me actually idk what im talking abt

west crow Dec 22, 2022, 11:42 PM

#

seems like the java executable is wrong

west coyote Dec 22, 2022, 11:42 PM

#

should i try reinstalling minecraft?

#

since it has bundled java it uses

west crow Dec 22, 2022, 11:42 PM

#

like that Minecraft wants some specific Java version

#

but you are using a different one

#

if you can get it to use the bundled Java version, it might work

west coyote Dec 22, 2022, 11:47 PM

#

ok well good news, it's giving me a different error now

#

well. thank you for your help but it's very late for me now and i am just going to make myself cry with frustration
i'm still getting the incompatible java error even after setting the path to the bundled java (tried both java.exe and javaw.exe, same error) so im. so unsure
