There is no 1.12 version of that mod. You will have to wait for the author to update it. *edit: Mod project page: https://minecraft.curseforge.com/projects/mumblelink

A quick search of the forums gave me this thread, have you run the vanilla minecraft 1.11.2 at least once?

Please post the entire logs/fml-client-latest.log file in spoiler tags.

Show a screenshot of your logs folder, and the launcher configuration for the forge profile, so we can know you're looking in the right spot

That's the version of forge you are using; are you using the official minecraft launcher (version 2.0.1003 is the latest as far as I can tell, shows at bottom left corner of launcher screen), or a 3rd party launcher

Please post the logs/fml-client-latest.log file, inside spoiler tags (the eyeball button above where you type your post)

Have you tried running the jar installer instead of the windows .exe installer?

If your filename is really uppercase, I think it needs to be lowercase.

Both registry name is the name of the thing, it will append the modid for you. then you can setUnlocalizedName(getRegistryName.toString()) The registry name will be the name of the textures/models

Yup, depending on what it's running on, it can take a couple minutes. Good luck!

Well the best I have is to contact the modpack author, as if other stuff runs fine, and that one doesn't, it would make me think there's an issue with the modpack. Maybe someone else will come along and see this and know more about it. Here's hoping!

Make sure you're using java 1.8 java -version from the same place you're running the server should tell you what version it's using by default

I honestly have no idea what is causing that crash. To me, it looks like your minecraft installation is broken Maybe try deleting/reinstalling the modpack? If you make a new profile, and don't choose any mods, just a basic forge setup, does it launch?

On the screen that shows the modpacks you have installed, right-click on the modpack, and choose Open Folder. That'll bring you into the folder that contains the logs folder, which should contain the fml-client-latest.log

Good deal. Also, when you're going to post it, before you paste it, click the eyeball button to post it in spoiler tags. Makes the page much easier to follow.

Depends where you are launching minecraft from. I saw a mention of curse in there, so if you're using the twitch client, there should be a button in the profile options to open the containing folder, and within there should be a logs folder containing that file.

Please post the logs/fml-client-latest.log file

Yeah it looks like you're attempting to use gui/client stuff on the server. You should post your code to a github repo and link it here for people to take a look. Posting snippets or individual classes usually doesn't provide enough information to pinpoint the issue.

Sorry, Minecraft 1.7.10 is no longer supported here. It is advised to use the latest version for mod development.

This is a fresh install right? You didn't copy it it over your old 2.5 install? Also, which version of java are you using?

Windows explorer (file browser) is not the same as Edge (web browser). Press the windows key + E to open windows explorer.

1.7.10 is also no longer supported here FYI

- Are you running your server from a batch (.BAT) file? If so, check that for the 256M setting. - Open a command window, and type SET and you will get a list of your environment variables. Look through them and see if there are any Java options in there with the 256M setting. If there are, you will need to go into your system settings to remove them. https://winaero.com/blog/how-to-edit-environment-variables-quickly-in-windows-8-1-and-windows-8/

Also just noticed, this is 32-bit java, you're likely to run into memory issues. I'd remove it and install the 64 bit (it will say 64 bit on the HotSpot Client line when you have it)
