Aristois 1.18 crashes at startup

taishor

Aristois 1.18 crashes at startup, vanilla 1.18 works fine. No mods, have tried delete everything under .minecraft and let launcher populate it again.

Are you using the official launcher? It's saying that your java version is incorrect. Ensure that you use version 17

@dyiing I reinstalled minecraft launcher by microsoft store now but same problem with crashes when trying to use Aristois 1.18. Vanilla 1.18 works fine.

Your files are outdated. Follow this:

Navigate to your .minecraft folder, then go into libraries.
Delete the EMC folder.
Delete the net folder.
Delete the me folder.
Reinstall Aristois.
Start the game

@dyiing

Deleted net and me folders as instructed, EMC folder don't exist because I never got Aristois 1.18 to run. Reinstalled Aristois 1.18 donar version.

Same problem at startup, crashes.

Did you re-download the installer? You cannot use an old one, you must get a new one.

If you did, please upload your json from .minecraft/versions/1.18-Aristois/

Apologizes, I downloaded Aristois 1.18 donor version 401 from homepage and now it works to play MC.

Recommend anyone still having the same problem starting MC Aristois 1.18 to download Aristois again from homepage... even if you did so recently
