How do I force my launcher to use Java 8?
I recently started getting the warning upon starting Minecraft SB3 Departed.... "[Immersive Engineering] Warning: your Java version is 1.8.0_25. This causes crashes with the Engineer's Manual...........You can prevent the crashes by installing up-to-date Java, (make sure you use Java 8 not Java 9) and forcing your launcher to use it."
So how do I get my launcher to use Java 8? Thanks
