help, forge wont install and I have tried just about everything

[A Lamp]

I downloaded forge and every time I run it I get a .txt file that says: 

Exception in thread "main" java.lang.ExceptionInInitializerError
    at net.minecraftforge.installer.ClientInstall.getSponsorMessage(ClientInstall.java:401)
    at net.minecraftforge.installer.InstallerAction.getSponsorMessage(InstallerAction.java:60)

I've tried just about every trick I can find online and nothing seems to work.  I am at lost what I need to do.  If anyone can help that will be greatly appreciated.

because you are using an old non-working installer
Your (old) version is no longer supported on this forum.
Please update to a modern version of Minecraft to receive support.

Some Old installers currently do not work, Use latest for your version
