1. Check Minecraft Forge Version.
The first thing that you should check if you are having problems installing Minecraft Forge on your computer is the version of the software that you are installing. Minecraft Forge requires that you install the same version of Minecraft: Java Edition to your computer for it to run properly.
If you are installing Minecraft Forge version 1.12, then you should also have the Minecraft: Java Edition 1.12 installed on your computer. You can verify this by going to Minecraft’s main screen. The version of the game would be indicated at the lower-left portion of the screen.
Now, once you know the version of Minecraft: Java Edition installed on your computer, go to Minecraft Forge official website and download the version that matches the version of Minecraft: Java Edition installed on your computer.
Also, make sure that you download the correct version for your operating system. If you are using a 64-bit version of Windows make sure that you also use the x64 version of Minecraft Forge installer and x86 for a 32-bit version of Windows.
2. Update Java on Your Computer.
One of the most common causes of Minecraft Forge installation problems is outdated Java software installed on your computer.
Minecraft is built around Java and if your system is not running the latest version of it, then it can cause performance issues including problems with installation of mods.
To update the Java software on your computer, you can follow the steps below.
- On your computer, press on the Windows Key + S on your keyboard and search for Java.
- Next, click on Configure Java to open its Settings.
- Lastly, go to the Update tab and click on Update Now.
Wait for the update to complete, then try installing Minecraft forge on your computer to see if the installation problem would still occur.
Now, if updating the Java software on your computer did not solve the issue, then you can proceed to the next method below.
3. Temporarily Disable Your Security Firewall.
Since Minecraft Forge is a modding platform for Minecraft, it can be falsely detected by your firewall as a malicious program since it is trying to change or mod system files of the actual Minecraft game. To bypass this, you can temporarily disable your system firewall until you have installed Minecraft Forge on your computer.
You can follow the steps below to guide you through the process.
- Press on Windows Key + S on your keyboard and search for Windows Firewall.
- Now, click on Open to launch the Windows Defender Firewall menu.
- After that, click on Turn Windows Defender On or Off on the side menu.
- Lastly, select Turn Off Windows Defender Firewall and click OK to save the changes.
Now, you can try installing Minecraft Forge on your computer to check if the installation problem would still occur after disabling Windows Firewall.
4. Reinstall Java on Your Computer.
The next thing that you should do if you are still having problems installing Minecraft Forge on your computer is to reinstall the Java software. It is possible that the current Java software installed on your computer got corrupted during use or it is not installed properly.
To ensure that you have a fresh copy of the Java software, it is best that you uninstall Java first, then redownload it on your computer.
- On your computer, press the Windows Key + S and search for the Control Panel.
- Now, open the Control Panel and click on Uninstall a Program.
- After that, scroll down and find the Java software from the list of programs installed on your computer.
- Lastly, right-click on Java and click on Uninstall.
Now, after uninstalling Java on your computer. You can go to their official website and download the latest version of Java and install it on your computer.
After that, try installing Minecraft Forge on your computer to check if you would still encounter Minecraft Forge installation problems.
5. Use Command Prompt to Launch the Installer.
Another thing that you can try is to install Minecraft Forge using the Command Prompt on your computer. Command Prompt is used to perform advanced administrative tasks and usually has more system privileges compared to using the normal file explorer on your computer.
To install Minecraft Forge using the command line, you can follow the step-by-step guide below.
- On your computer, go to the Downloads folder and find the Minecraft Forge installation file.
- Next, rename the forge-installer.JAR file to forge.JAR.
- After that, hold the left-shift key on your keyboard and right-click on the menu.
- Now, click on Open PowerShell Window Here.
- Lastly, type java -Xnx2G -jar forge.jar? and hit Enter.
Now, this will launch the Minecraft Forge installer. Follow the on-screen prompts to install the program on your computer.
However, if the installation still failed after using the Command Prompt. You can proceed to the last method below to try and fix the issue with Minecraft Forge installation.
6. Check Your Internet Connection.
The last thing that you should do if you are having problems installing Minecraft Forge on your computer is to check if you have a stable internet connection.
Even if you already download the installer on your computer, Minecraft Forge would still need to download several library files for the installation process to complete.
However, if you have an unstable internet connection, then the installer might have difficulty downloading the library files which causes the Minecraft Forge installation problem.
To verify this, you can try doing a speed test to check if you are getting the correct speed bandwidth from your ISP (Internet Service Provider). You can try using a third-party website like Fast.com (Provided by Netflix) which can effectively measure both your upload and download speed to verify if there is an underlying issue.
Now, if your speed test result comes out slow or not close to the specified internet speed bandwidth based on your monthly subscription. You can try restarting your internet router.
To do this, locate and remove the power cable of your router which is typically located at the back, then wait for at least 5 – 10 seconds before plugging back the power cable. Now, perform another speed test to check if you are getting the correct internet speed from your ISP.
However, if the issue still persists after restarting your router. The best thing to do is to contact your Internet Service Provider and report to them the issue that you are experiencing with their internet service.

Hello! I am trying to download an older version of forge for a certain mod, but after I’ve downloaded the file it won’t open. Any help?
ive tried all the things, but it still doesnt work. and when i type in the command it responds with: Error: Unable to access jarfile forge.jar?
mine said the same thing were you able to find a solution?
First, make sure you renamed the file ‘forge.jar’ and not ‘forge.jar.jar’. In file explorer, click View > Options > Change folder and search options > View, and then uncheck Hide extensions for known file types. Then click OK and you will see the full name of the file.
If it is named properly, use this command instead: ‘java -Xmx1024M -jar forge.jar -o true’. That worked for me. Some people are also saying that they have trouble if they copy-paste it into powershell but if they type it, then it works.
