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

I am using Windows 10 and when I open the forge-11.16.4-35.1.4.jar file nothing happens.
Also another bug with 1.8's server, it doesn't even work.
yes ik that 1.8 isn't supported but if anyone can help me with both feel free to.
