Recommended Posts

I'm trying to install forge for 1.14.4 specifically but i tried going back to 1.14.3 and 1.14.2. Every time I try to install i get this error that tells me not all of the libraries were installed and to try again. Some help would be greatly appreciated. :) Here is a link to a screenshot of the error window: https://imgur.com/JIdr4qU

    • Hi, I have a problem because when i start minecraft with forge 40.1.20 the game don't open. Someone help?  
    • update to the latest version of Forge, also 1.16.5 requires java 8
    • one of your mods requires GeckoLib, unfortunately is this mod not declared its dependencies correctly to Forge, so Forge can not show you a warning. If you find out which Mod requires GeckoLib report this issue to the Mod author
