[1.12.2] Can't start Forge, help?

[MadBrains]

Hi there, been having problems for the entire time while trying to set up a server. I don't know why this is happening and need any kind of help with this. I've been Googling for the past 3 hours and to no avail ): . So any help would be great!

 

Thank you in advanced!

 

Also forgot to mention, I have been also trying to run the .jar universal that extracts from the installer, but nothing comes up either.

Java 9 is not currently supported, you need to use Java 8.

I installed 8, but now it's not finding Java on my computer.

then you've messed up your PATH variable, you can run java by typing the full path to the java exe instead of the word 'java'
