Java runtime manifest is missing when launching Minecraft

If you have not been able to fix this yet, I recommend downloading Java 17 and forcing your Minecraft Launcher to launch the snapshots through it.

You can do this by selecting More Options when editing instances and selecting Java 17 when choosing the Java Executable. I found this website helpful for more information: https://minecrafthopper.net/help/guides/changing-java-version/

Hope this helps!

This is also a problem in Prerelease 1. Here's proof:

I can confirm this still happens in 1.19-pre1

I have Java 8 installed, and I tried re-installing it. The bug persisted.

(I am going to try Java 17 next)

Java 17 works properly for me.

Given that long-term support for Java 8 ended in March of this year, this ticket may not be classified as a bug.

This would mean that many players will need to update java to play the 1.19 update, which they should probably do anyway for security reasons.

lvjoo it dont work i get this message when i tried ite               
Failed to find Java Runtime. Error Details: The operation was completed. File name on disk: java Path: C:\Program Files\Java\jre1.8.0_281\bin\java Exists: Nonexistent

i have download java 17, but my minecraft does still have the same problem.

https://minecrafthopper.net/help/guides/changing-java-version/ works, i have solf it, the thing i have need to type was wrong but now i can play minecraft 1.19 😀

This worked perfectly. Thank you!

edit: For clarity, it was forcing the launcher to use the updated Java using "other options" that worked.  Thanks!

@uzumaki_asta It looks like the launcher is still trying to use Java 8. Make sure that you've got Java 17 installed and that you're pointing the launcher to the correct javaw binary.

Per the dev team, this should now be resolved!
