How to Repair a Corrupt or Invalid Jarfile in Minecraft Forge
1. Double-check that the download is complete.
You’ll receive a variety of problems if you attempt to run the game before it’s finished downloading, including the invalid or corrupt jarfile error.
Check to see whether Minecraft Forge has shown in your downloads folder. Then, make sure it’s not being blocked by your browser for any reason.
Recover the file in your browser’s download manager and try again.
2. Switch to a different browser.
Many of the customers who reported invalid or corrupt jarfile problems in Minecraft downloaded the game using Firefox.
The Minecraft Forge download seems to be often blocked by Firefox. As a result, we recommend that you try downloading the game using a different browser.
3. Install the most recent version of Java.
Make sure your computer has the most recent Java version installed. If you’re using an older version, download a newer one.
4. Turn off all background applications.
Remember to close all background applications and processes before installing Minecraft Forge or any other game or software on your computer.
Some of the applications that are currently operating on your computer may prevent the download from taking place. Alternatively, they may cause Minecraft Forge to crash when you attempt to load the launcher.
Using Task Manager or a clean start of your computer, you may close background applications.
If you’d rather utilize Task Manager, go to the Processes tab and right-click on the applications you wish to turn off. Then choose Finish Task.
You may also turn off your antivirus and firewall for a while. Certain Minecraft files may be erroneously flagged as suspicious by these applications, causing them to be blocked.
After you’ve downloaded and installed Minecraft Forge, remember to re-enable your antivirus and firewall.
