Run the Minecraft Installer Launcher then try installing Forge again

Please do not hijack threads, if you have an issue please make your own.

Check the very bottom of the list Edit: Wait are we talking Installations or Versions here?

Check the bottom of the versions list

For whatever reason 1.12.2 versions of Forge get sorted to the bottom of the list.

Your Forge file is called forge-1.12.2-14.23.5.2768-universal.jar, not forge-1.12.2-14.23.5.2768.jar

Provide a screenshot of your server folder. Also Judging from your Java path you have 32-Bit Java, this is likely to create problems later and I would recommend installing 64-Bit Java. https://adoptopenjdk.net

What is in your bat file and what does the command prompt show?

Structure of a Command: [Command or Program to Invoke] [Arguments to apply to the Command] You have the arguments but not the program. Find where Java is installed on your computer and use the full path of the java exe to invoke it

You go into your .minecraft folder, go into the mods folder, find the folder that is named for your current Minecraft version, and delete the otg component from there. https://minecraft.gamepedia.com/.minecraft#Locating_.minecraft

OTG installs a component of itself into a mods/mcVersion folder, this component gets loaded and crashes when the main mod jar isn't found, you'll have to delete it manually.

In the command window you provided before, you put in the arguments for running Java but you didn't include the java invocation

Update to the latest version of Java 8. https://adoptopenjdk.net

and you're so worried about possibly leaking info that you're afraid of providing a log that would help me identify your issue

Not sure I understand what you're saying... are you saying what I'm asking you to do is sketchy?

Please restart your launcher and launch the game, then quit and immediately provide your launcher_log.txt from .minecraft

Do you have Forge installed?

What do you mean you're unable to use it?

1.8.9 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

Forge is what allows almost every mod to work in the first place, you know...

Try running the Forge installer again

The filenames of some of your mods suggests you are not getting them from official sources, please read my signature for more info on why this is a bad thing. <rant> Why does everyone need a tutorial for installing a Forge server? Download Forge installer from https://files.minecraftforge.net Run installer Select Server Install Select Server Directory Click Install If you have problems, come here with the installer log </rant>

1.7.10 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

Please provide your installer log, it will have the same name as the installer but with .log on the end: Installer: forge-{version}-installer.jar Log: forge-{version}-installer.jar.log Note: If you have Windows Explorer set to hide file extensions(as is the default setting), they will look like this: Installer: forge-{version}-installer Log: forge-{version}-installer.jar

Did you just say you removed Forge because you got your mods and didn't need it anymore?
