When I try to run the forge .jar file, I get this error in cmd prompt, and don't know what to do. 
 

The forge.jar is forge-1.12.2-14.23.5.2854-universal.jar, just renamed.


C:\Forge Server>java -Xmx16384M -Xms16384M -jar forge.jar nogui

1.12 is no longer supported on this forum. Please update to a modern version of Minecraft to receive support.

It's sad how much time mods spend saying "x is no longer supported on this forum. Please update to a modern version of Minecraft to receive support".
