Hi, I’m trying to run a forge server with mu friends, but when I open the forge .jar archive it won’t open and when I try to open .bat archive it won’t open neither. I tried installing Java 8 and it doesn’t work. I have windows 10. Thanks

run the server via command line and post output

which forge and java version did you use

Java version 8 and forge version 2854, but I tried with some other Forge versions like 2838 and 2855.

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