Hi guys i had this problem. I usualy play minecraft modded or not in java 7 64-bit . Yesterday i play with my friend minecraft vanilla and for server need java 8 SDK 64bit .Now went i click on skcraft launcher apear "The registry refers to a nonexistent Java Runtime Enviroment installation or the runtime is corrupte". I try to fix but i cant . PS: ftb launcher , technic launcher and atlauncher work
Ok...I have absolutely no idea what just happened - but if this problem ever happens to come up again, let just leave a solution here as to check the Windows Registries for out of order keys.
