    I am using the Java Version
    Java(TM) SE Runtime Environment (build 1.8.0_321-b07)
    Java HotSpot(TM) 64-Bit Server VM (build 25.321-b07, mixed mode). That should be the newest.

    Hi, i have this same problem, i tried installing the java 17 version, but doin it, i was unable to launch minecraft because the launcher use a more recent version of java.
    i tried unnistaling and reinstaling java, and didt work either. Also tried to mount a server with the original java file that the oficcial minecraft page gave me, and had the same problem, its like im stuck on the recompile version 52 when im using the last update of java, and i have no idea what to do to change it.

    hoping someone know what to do. Cya

    @matblader Need to change the "java" to the full path of the java.exe, it is still using the old version.
