Recommended Posts

So recently I bought Minecraft and decided to add some mods. so when I went to install Minecraft forge, it would not work. I try to install it but nothing happens. can someone please help me understand either what I'm doing wrong or what is going wrong with the installation.

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

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Spoiler

Logs (Most issues require logs to diagnose):

Spoiler

Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

https://gist.github.com/100MB Requires member (Free)

https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

https://hastebin.com/: 400KB

Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

 

What to provide:

...for Crashes and Runtime issues:

Minecraft 1.14.4 and newer:

Post debug.log

Older versions:

Please update...

 

...for Installer Issues:

Post your installer log, found in the same place you ran the installer

This log will be called either installer.log or named the same as the installer but with .log on the end

Note for Windows users:

Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

 

Where to get it:

Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

 

Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

Spoiler
  1. Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
  2. Make a launcher profile targeting this version of Forge.
  3. Set the launcher profile's GameDir property to the pack's instance folder (not the instances folder, the folder that has the pack's name on it).
  4. Now launch the pack through that profile and follow the "Mojang Launcher" instructions above.

or alternately, 

 

Fallback ("No logs are generated"):

If you don't see logs generated in the usual place, provide the launcher_log.txt from .minecraft

 

Server Not Starting:

Spoiler

If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.

 

Reporting Illegal/Inappropriate Adfocus Ads:

Spoiler

Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.

Lex will need the Ad ID contained in that URL to report it to Adfocus' support team.

 

Posting your mod as a GitHub Repo:

Spoiler

When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.

When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.

 

  1. Open a command prompt (CMD, Powershell, Terminal, etc).
  2. Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
  3. Run the following commands:
    1. git init
    2. git remote add origin [Your Repository's URL]
      • In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
    3. git fetch
    4. git checkout --track origin/master
    5. git stage *
    6. git commit -m "[Your commit message]"
    7. git push
  4. Navigate to GitHub and you should now see most of the files.
    • note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
  5. Now you can share your GitHub link with those who you are asking for help.

[Workaround line, please ignore]

my apologies but I am not a very tech-savvy person so I have no idea what an installer log is or how to find it

You downloaded the installer, right? That comes as a jar file. When you run it, it will produce the log file next to it.

well when you go to Minecraft forge I press the "installer" button for the 1.14.3 version. it saves to my downloads but after that I have tried to open it. it opens with internet explorer and asks me if I want to open it or save it. I have tried doing both but nothing really happens

Open your windows terminal and write java -version, can you send what it shows ?

Why did you not mention this in the first place? Your first post says it does "nothing", which is obviously not true...

Make sure you have Java installed, if you do, you can run Jarfix to fix the jar-file association.

hey, go here and install this. Once it's installed, go to your downloads folder and rerun the program, problem solved. 

 

Edit: I made an account for this ^-^

looking back at my first post I definitely should have been more descriptive. so I downloaded Java and tried to download Jarfix and it said that I didn't have Java installed.....

There is only one good way to know if java is well installed...

Go in your windows command prompt and type java -version

can you send me a screen of what you'll get ?

so I did not know what windows command prompt was either, so I looked it up and did what they said and typed java-version and I got the first picture, but then I realized I typed it in wrong and retyped it and got the 2nd picture

Ok now, the installer in .jar should have the java logo on it.

When you double click on it, it should open a white window, is it the case here ?

unfortunately it does not. it has the internet explorer logo on it. and when I open it this is what I see (2nd pic)
