How to Fix the “Invalid Version Type” Error in Minecraft

When launching Minecraft, encountering the “Invalid Version Type” error typically results in the game failing to start or update correctly. This error occurs when the launcher does not recognize the specified game version, often due to incorrect installation of a mod profile or when the host file is configured incorrectly, blocking the required Minecraft services. Corrupted files located in the Minecraft installation directory are also one of the main causes of this issue.

Now that we’ve discussed the potential causes, let’s explore the verified solutions to resolve the issue.

1. Reinstall the Mod Profile

Over time, mods can become corrupted or outdated, causing the Minecraft launcher to display this error message. By reinstalling the mod profile, you will ensure that all mod-related files are correctly installed and compatible with the current version of Minecraft. This will also remove any corrupted files that might be causing the mismatch, resulting in this error message.

1. From the Minecraft Launcher, go to the Installation tab.
2. Find the installed mod, whether it is Forge or any other mod, click the three dots, and select Delete.
   
3. Once the mod has been deleted, visit the mod’s official website to download the mod installer.
4. Open the installer and follow the on-screen instructions to install the Mod Profile.
5. Launch Minecraft with the mod and see if the issue is resolved.
   

2. Check Host Files

The Host file may contain entries related to Minecraft or the Mojang launcher, preventing the launcher from opening Minecraft. The host file is a text file that is used to map hostnames to IP addresses, functioning as a local DNS in the system to resolve domain names into IP addresses.

In addition, the host file can be utilized to block or redirect traffic to a specific website. However, if this file contains entries related to Minecraft, you won’t be able to launch it unless you remove all the entries. Therefore, make sure to check the host file to ensure that it does not block Minecraft.

1. Click the Start Menu and type Notepad.
2. Right-click on it and select Run as administrator.
   
3. In Notepad, click File and then Open.
4. Navigate to the following destination and select the host file. Then, click Open.

   C:\Windows\System32\drivers\etc\host

   

5. Once the host file is opened, remove all the entries related to Minecraft or Mojang.
6. Press Ctrl + S to save the file.
   
7. Check if the error persists by launching Minecraft.

3. Switch to a Different Launcher

If the issue is not resolved, consider switching to a different launcher to bypass the issues related to the launcher and the game. Since your launcher has compatibility issues with Minecraft, switching to a different launcher, such as MultiMC or ATLauncher, should resolve the error message.

1. Head over to the launcher’s official website to download and install the launcher.
   
2. Set up the launcher for Minecraft by installing the latest Java version and creating a new instance for Minecraft. Additionally, you can install the Forge Mod Loader.
3. Launch Minecraft, and you should be good to go.

Lastly, it is recommended to perform a clean installation of Minecraft to ensure all files are correctly installed and free from corruption, especially if the previous solutions did not resolve the error message.

By reinstalling Minecraft, you ensure that you are running the latest version and that all dependencies and configurations are set correctly. This eliminates the chances of conflicts from the mods and files, allowing the user to experience error-free gameplay.
