In this guide, we will walk you through a simple method to resolve this issue and enable smooth gameplay.

Step-by-Step Guide

Step 1: Open the Project Launcher App

• Begin by launching the Project Launcher app on your device.

Step 2: Download Minecraft Version 1.7.10

• In the launcher, download Minecraft version 1.7.10. This version can serve as a base for further modifications.

Step 3: Launch and Close

• Open the downloaded version to initialize it. Once it is launched, close the app to properly save the settings.

Step 4: Choose Your Desired Version

• After closing the initial version, choose the version you wish to play— in this example, we'll select version 1.16.5.

Important Note

• Do not enable your internet connection while playing on PojavLauncher, as it can lead to complications or revert your settings.

Step 5: Check Launch Settings

• You might notice that even after selecting version 1.16.5, the launcher defaults to 1.7.10. This is where file management comes into play.

Step 6: Required App Installation

• It is necessary to have an app called ZArchiver. Download and install this app to help manage your Minecraft files.

Step 7: Navigate to PojavLauncher Directory

Step 8: Access the Version Folder

• Locate the version folder. Within this, find the files associated with Minecraft version 1.16.5.

Step 9: Copy and Paste Files

• Copy all the files from the 1.16.5 folder and paste them into the 1.7.10 version folder.

Step 10: Rename Files

• Make sure to rename the copied files to match the naming convention of the original 1.7.10 files. This step is crucial for the launcher to recognize the new files.

Step 11: Relaunch the Project Launcher

• After completing the steps, open Project Launcher again. Remember to keep your internet connection off during this process.

Result
