Minecraft forge profile doesn't launch


Recommended Posts

Hi, I was going to test a mod with forge but when i click to play the launcher closes and nothing happens :( . The only thing i did the last days related to java or Minecraft was installing the java JDK v8 ,including in the path variable the route of instalation of java JDK and installing a tool for quick mod develop called Mcreator. The last log:

I've stopped counting the number of times I have answered this. Please for the love of god. Read the EAQ or at least search before you are posting.
