Downgrading Modules

Downgrading a Module in Foundry VTT

At times, you might need to downgrade a module to a previous version in Foundry VTT, especially when dealing with compatibility issues with your Foundry or game system version. This guide walks you through the process of downgrading a module.

Downgrading a Module for Your Current Foundry VTT Version

If a module is installed for the wrong Foundry VTT version, you can easily downgrade it by uninstalling and reinstalling the module. Foundry VTT automatically installs the correct version of the module based on your current Foundry version.

Steps:

  1. Uninstall the module: Go to the Add-on Modules section of the Foundry VTT setup screen and remove the module.
  2. Reinstall the module: Once uninstalled, reinstall the module. This will ensure that the version matching your current Foundry VTT version is installed.

Note: You will need to do this if you've downgraded your Foundry VTT version and now have a module that is designed for a newer Foundry version than the one you're using.

Downgrading a Module for a Specific Game System Version (Manual Downgrade)

If a module version is incompatible with your game system (e.g., D&D 5e, Pathfinder, etc.) or you want to manually downgrade to a specific version for other reasons, you'll need to install the module using a specific manifest URL. This allows you to install the exact version that works with your game system.

Steps to Manually Downgrade:

  1. Visit the module's page on the Foundry VTT website.
  2. Find the desired version: Look for the version you need based on your game system. For example, if you're using D&D 5e v3.x, look for the latest module version that also starts with v3.x to match compatibility.
  3. Copy the manifest URL: Scroll down to the version history, find the appropriate version, right-click the Manifest URL link, and select "Copy Link Address".
  4. Open Foundry VTT: On the Foundry setup screen, go to Add-on Modules and click the Install Module button.
  5. Enter the manifest URL: At the bottom of the installation window, paste the manifest URL you copied in step 3 into the Manifest URL field.
  6. Install the module: Click Install, and the selected version will be downloaded and installed.
