I am following the steps to set up a modded 1.16.5 minecraft server because I want to run mod packs that only are available on this version and I am stuck at this part of the setup (https://youtu.be/bIjisWyxU-8?t=472) where running the .bat file is supposed to generate the folders files and eula text document needed to continue with the setup process, however for me the .bat file only generated the logs folder.

Here is what's generated by the cmd window:

thank you for replying to me so quickly you're amazing!

I tried downloading Java 8 JRE version 311 and it didn't work, did I download the wrong version? sorry this isn't exactly my area... When you say download Java 8 which link are we talking about? This is the link I used

I tried uninstalling Java 17 and downloaded the most current version of Java 8 here https://www.java.com/download/ie_manual.jsp and maybe that's fixed that bug ? i may have downloaded the wrong java 8 idk what i'm donig to be honest... anyways now it's displaying another issue with the .bat that says 

C:\Users\brian\OneDrive\Desktop\SERVER FOLDER>java -Xmx4096M -Xms4096M -jar server.jar nogui
Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I have 16 GB of RAM installed on this PC so i'm confused why specifying for 4GB isn't working. I originally had it at 12 then 8GB and the same message. I won't know if the java fix is working until i fix this one too i suppose :/

I tried decreasing it down to 3GB just for kicks and giggles even though i know this won't be nearly enough RAM and this is the message that i get.

C:\Users\brian\OneDrive\Desktop\SERVER FOLDER>java -Xmx3072M -Xms3072M -jar server.jar nogui
Error occurred during initialization of VM
Could not reserve enough space for 3145728KB object heap

I have a feeling that no matter what I input for the max it won't matter :/

    • Hi! I've been running a server on Minecraft using the Prodigium Reforged pack on curse forge using the site exaroton. It was working fine until randomly encountering this error every time anyone tries to connect to the server, I've already reloaded backups and deleted json files  Here is the crash report https://mclo.gs/EwKw51q. Thanks for the help in advance
    • nevermind i figured out the issue  
    • I was trying to host a server with the 1.21.1 cobbleverse forge mod, but when I tried starting it, it kept giving me this error. Crash report here: https://pastebin.com/AsE1X5QY   Thanks
    • This mod lets you choose an element power, Earth, Wind, Fire, or Water. Also two secret element powers Light and Darkness. Each power gives good a bad things, Earth lets you dig through anything but ores and bedrock, Wind lets you jump high in the air every three seconds, Fir lets you throw fire balls and you are immune to any flame/lava but you can't go into water or else you take damage, Water you swim and break blocks under water quicker and you can get rid of water like a sponge but you take more damage when in fire/lava, Light makes you faster at day but slower at night you are able to throw light spears that do four hearts and can go through any armor, Darkness let's you be faster at night but slower at day mobs don't harm you but peaceful mobs run away from you you are able to spawn ink creatures around you that are like dogs but are stronger. another thing in the mod is that there are other dimensions that can get you ores to make better armor and weapons, each dimensions are are good for a certain element though each dimension has a boss depending on which dimension one dimension has more than one boss, each elements are required to defeat the bosses with each others help.
    • Read the posts above yours, it tells you exactly how to do it, instructions are the same if it's making a forge installation or a vanilla one, just make a new folder for the game directory.
