Step 1: Verify Game and Mod Updates

Baldur’s Gate 3 and its mods frequently receive updates. An outdated mod or game version is one of the most common reasons for the “Failed to Read PAK” error.

1. Update BG3:
– Open your game launcher (Steam, GOG, etc.) and ensure BG3 is updated to the latest version.
– If the game receives frequent updates, this could mean mods need updating as well to remain compatible.

2. Update Mods in Vortex:
– Open Vortex and navigate to the Mods section.
– Check for any notifications about updates. If there are updates available, update each mod individually.
– This can solve compatibility issues causing the PAK error.

Step 2: Clear and Reinstall the Mods

A corrupted or improperly installed mod can also lead to this error. Try clearing out the mods and reinstalling them through Vortex.

1. Uninstall Mods:
– In Vortex, go to Mods and Remove any mod causing the issue.
– Try disabling all mods temporarily, then restart Vortex.

2. Reinstall Mods:
– Download fresh copies of the mods from a trusted source, such as Nexus Mods.
– Install them again through Vortex and enable them.
– Test if the “Failed to Read PAK” error persists. Often, a fresh installation resolves the problem.

Step 3: Verify Mod Deployment

Sometimes, Vortex fails to deploy mods correctly. Ensure that the mods are deployed properly.

1. Check Deployment:
– Go to Settings in Vortex, then Mods, and ensure the correct game path is selected.
– In the Mods tab, click on Deploy Mods to reinitiate the mod installation.

2. Deploy Individually:
– Try deploying individual mods instead of deploying all at once. This can help identify if a specific mod is causing the issue.

Step 4: Check Game Data Path Configuration

Incorrect game data paths in Vortex can also cause PAK reading errors.

1. Set Correct Data Path:
– In Vortex, go to Settings > Mods and confirm that the BG3 game path is correct.
– Navigate to File Settings in Vortex and re-check the Staging Folder path to ensure all mod data is accessible.

Step 5: Use the Manual Method

If Vortex continues to produce the error, try installing mods manually.

1. Install Mods Directly in the Game Folder:
– Download mod files manually and extract them.
– Place the extracted files in BG3’s Mods folder (`C:\Users\YourUsername\Documents\Larian Studios\Baldur’s Gate 3\Mods`).
– Modify the modsettings.lsx file in the profile folder to load the mods.

The “Failed to Read PAK” error in Vortex can be resolved with a few adjustments and reconfigurations. By verifying game updates, ensuring mods are properly installed, and double-checking your Vortex settings, you can clear this error and return to modding Baldur’s Gate 3 smoothly.
