Hi there!

When I launch my mine craft 1.12 version this pops up:

If you know why could you PLEASE help me with this problem!

Just so you know:

-I DO have Java 8 installed already

-I have a VERY old computer and that might be the problem

Exception in thread "main" java.lang.UnsupportedClassVersionError: net/minecraft/client/main/Main : Unsupported major.minor version 52.0Exception in thread "main" java.lang.UnsupportedClassVersionError: net/minecraft/client/main/Main : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:637) at java.lang.ClassLoader.defineClass(ClassLoader.java:621) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

Having Java 8 installed does not mean MC is using it, the error indicates it does not.

Does Minecraft need to use it? And if so how do I fix that?
