Baldur's Gate 3 is an incredibly popular role-playing video game developed by Larian Studios. However, like any other game, it is not immune to technical issues. One such issue that players may encounter is the Baldur's Gate 3 Launcher Data Mismatch. This problem can disrupt gameplay and prevent players from fully enjoying the game. In this blog post, we will provide you with a comprehensive guide on how to fix this issue, ensuring a smooth gaming experience.

Verify the Integrity



Before diving into the various solutions for the Baldur's Gate 3 Launcher Data Mismatch issue, it is crucial to verify the integrity of your game files through the launcher. This step is essential as it helps identify any corrupted or missing files that may be causing the data mismatch problem. To verify the integrity, follow these steps:

  • 1. Launch the Baldur's Gate 3 launcher.
  • 2. Go to the game's settings or options menu.
  • 3. Look for an option to verify the integrity of game files.
  • 4. Click on the verify button and allow the process to complete.


Deleting Installed Mods



Mods can enhance gameplay and add new features to Baldur's Gate 3. However, they can also cause data mismatch issues, especially if they are not compatible with the current version of the game. If you have installed mods and are experiencing the Launcher Data Mismatch problem, it is advisable to delete them. Follow these steps to delete installed mods:

  • 1. Locate the folder where the mods are stored. This is usually in the game's installation directory.
  • 2. Open the mods folder and select all the files present.
  • 3. Delete the selected files permanently or move them to a different location outside the Baldur's Gate 3 folder.


Renaming the Larian Studios Folder

Renaming the Larian Studios folder is another potential solution to fix the data mismatch problem. By doing this, you essentially force the game to create a new folder with fresh files, eliminating any potential conflicts. Here's how you can rename the Larian Studios folder:


  • 1. Close the game and exit the Baldur's Gate 3 launcher if it's running.
  • 2. Navigate to the installation directory of Baldur's Gate 3.
  • 3. Locate the Larian Studios folder and right-click on it.
  • 4. Choose the "Rename" option and give it a different name (e.g., "Larian Studios_old").
  • 5. Restart the game and let it create a new Larian Studios folder.


Deleting Baldur’s Gate 3 Cache Files



Cache files are temporary files that the game stores to speed up loading times. However, if these files become corrupted or outdated, they can lead to a data mismatch issue. Deleting cache files can often resolve the problem. Follow these steps to delete cache files for Baldur's Gate 3:


  • 1. Close the game and exit the Baldur's Gate 3 launcher.
  • 2. Open the File Explorer and navigate to the following location: C:\Users\[Your Username]\AppData\Local\Larian Studios.
  • 3. Inside the Larian Studios folder, look for a folder named "Baldur's Gate 3" or similar.
  • 4. Delete the entire folder or move it to a different location outside the Larian Studios folder.
  • 5. Restart the game and check if the data mismatch issue persists.


Uninstall and Reinstall Baldur’s Gate 3



If all else fails, uninstalling and reinstalling Baldur's Gate 3 may be the last resort to fix the Launcher Data Mismatch issue. However, keep in mind that this should be a last resort due to the time and effort involved in reinstalling the game. Before proceeding, ensure that you have a backup of your saved games or any important files. Here's how you can uninstall and reinstall the game:

  • 2. Navigate to the "Programs" or "Programs and Features" section.
