Here’s the process to uninstall the corrupted mod:

  • Press the Windows key, type Run, and hit Enter.
  • Type %appdata% in the command box and click
  • Open the .Minecraft directory and go to mods.

Thus, copy and paste all the mods one by one and find the faulty mod out. Contact the developer and let him know the problem.

  • Launch Minecraft and select the options menu next to your username.

  • Install the update.

Hence, your Minecraft is installed. If this doesn’t solve your problem, move to the next one. You can also find saddles in Minecraft in a spawn chunk.

Windows Firewall can block access to a third-party application, like, Minecraft. So, you have to disable the Windows Firewall on your device. Follow the process to turn off the Firewall:

  • Click on the search option next to Windows, type Firewall & network protection, and hit Enter. You’ll end up in the Windows Security

Method 4: Replace the .jar file

If you haven’t set the Java or JDK as a default application opener for .jar and .java files, the issue you’re dealing with is caused by this. Here’s how you can replace the .jar file and solve your problem:

  • Press Windows key+R to open the Run
  • Type %appdata%\.minecraft\assets\indexes\ and hit Enter.indexes
  • Right-click on a .jar or .java file and select Properties.

Open the Minecraft launcher again and see if this solves your case.

Travel Different Minecraft Biomes and search for the pumpkin plants. If you don’t know which biomes contain which plant then, use the Minecraft Biome Finder app to locate the plants.

Method 5: Open the Vanilla Launcher

Almost 30% of the “Failed to download file” cases I solved personally with the help of the Vanilla Minecraft launcher. Here’s the process you can follow to solve yours:

  • Uninstall the non-Vanilla launcher.
  • Open the Vanilla launcher and click Play.
  • Close the Vanilla launcher when you see Create Game Screen.
  • Reinstall the non-Vanilla launcher you were using and check if the issue is clear.

But if you are a Twitch user, you need to follow the below-mentioned process.

  • Click on the Mod Pack and switch to the Vanilla launcher screen.
  • Open the game, allow it to load fully, and close it.

Repeat the same for the Mod Pack and see if the issue is gone.

Quick TIP: Learn how to kill all hostile mobs at once using the Minecraft kill Commands. You can use a Minecraft command block to execute the commands.

Method 6: Download the file with a VPN connection

Sometimes it’s the location that causes this problem. If the server in your region is down or getting disconnected, you might face the “Failed to download file” issue. You need to download the required file using a VPN connection to solve this. Here’s a simple process how you can download your file:

  • Open your browser and download a VPN.
  • Install it to your system and select a country with a different server. Suppose if you are in America, choose Germany or UK.
  • Open the launcher and see if the download file issue is fixed.

PRO  TIP: Use a Command Block to Execute the commands easily.

Method 7. Reinstall Minecraft

If none of the methods can resolve your problem, it’s time to reinstall Minecraft. A clean installation of Minecraft will eliminate all the faulty installation of Minecraft. Here’s the process to reinstall Minecraft:

  • Press the Windows key and type Run to open the Run
  • Type %appdata% and press OK.
  • Scroll down until you find the .minecraft directory and save the file to your portable hard disk or anywhere that is safe.
  • Press the Windows key, type Apps and features, and open it.
  • Find Minecraft and right-click on it.
  • Click Uninstall and confirm the process.
  • Restart your PC and again press Windows key+R to reopen the Run
  • Type %appdata% and hit Enter.
  • Delete the .minecraft folder, and open the Run prompt for the last time.
  • Type AppData and press Enter.
  • Go to the Local folder, delete all the Minecraft folders, and return to the AppData.
  • Navigate to the LocalLow folder, delete all the Minecraft folders and return to the AppData.
