How to Install and Manage After Effects Plugins

This guide explains how to install, organize, and manage third-party plugins in Adobe After Effects across both Windows and macOS platforms. You will learn the difference between automated installers and manual installation methods, standard file directory paths, techniques for using third-party package managers, and effective ways to troubleshoot or disable problematic plugins without uninstalling your software.

Understanding After Effects Add-ons

Before installing, distinguish between the types of add-ons available for After Effects:

  • Plugins (.aex files): Compiled software modules that add new effects, visual processing, or rendering capabilities directly into the Effect menu.
  • Scripts (.jsx or .jsxbin files): Code that automates repetitive tasks or modifies project elements.
  • Extensions (.zxp files): Custom panels with web-based user interfaces running inside the program.

Method 1: Using Automated Installers

Most commercial plugin suites (such as Boris FX, Maxon/Red Giant, and Video Copilot) provide dedicated installer files (.exe for Windows or .dmg/.pkg for macOS).

  1. Close Adobe After Effects completely.
  2. Run the downloaded installer file.
  3. If prompted, select your installed version of After Effects.
  4. Follow the setup wizard instructions to complete installation.
  5. Reopen After Effects; the tools will appear in the Effect menu or the Effects & Presets panel.

Method 2: Manual Installation (.aex Files)

If your plugin is distributed as an individual .aex file (or .plugin bundle on macOS) without an automated installer, install it manually by moving it into the correct directory.

Windows Directory:

C:\Program Files\Adobe\Adobe After Effects <version>\Support Files\Plug-ins

macOS Directory:

/Applications/Adobe After Effects <version>/Plug-ins

Steps:

  1. Close After Effects.
  2. Unzip or extract the downloaded archive.
  3. Copy the .aex file or the entire plugin folder.
  4. Paste it into the Plug-ins directory path listed above.
  5. Launch After Effects.

Method 3: Using Third-Party Plugin Managers

Many developers use centralized management applications to automate installation, licensing, and updates:

  • aescripts + aeplugins manager: Ideal for installing .zxp extensions, scripts, and plugins purchased through their store.
  • Maxon App: Manages Red Giant plugins (Trapcode, Magic Bullet, Universe).
  • Boris FX Hub: Handles licensing and updates for Sapphire, Continuum, and Mocha.

Using these platforms ensures that your plugins remain compatible with newer After Effects releases and update automatically.

How to Manage and Disable Plugins

Managing your plugins helps keep After Effects running smoothly and reduces startup load times.

Organizing Plugins

Inside the Plug-ins folder, you can create custom subfolders (e.g., _MyCustomPlugins or organize by vendor) to keep files tidy. After Effects scans subdirectories recursively.

Temporarily Disabling Plugins

If a plugin causes crashes or slow startup times, disable it without deleting the files:

  • Using a Tilde Prefix: Add a tilde (~) to the beginning of the folder or plugin name (e.g., ~OldPlugin.aex). After Effects ignores any file or folder starting with this character during startup.
  • Moving Files: Move the plugin files out of the Plug-ins folder into a separate storage directory on your drive.

Troubleshooting Missing or Broken Plugins

  • Version Mismatch: Ensure the plugin architecture matches your software version (modern versions of After Effects require 64-bit plugins, and Apple Silicon versions require native M1/M2/M3 support or running After Effects via Rosetta 2).
  • Clear Media Cache: Go to Edit > Purge > All Memory & Disk Cache to resolve rendering glitches caused by updated plugins.
  • Missing Plugin Warning: If a project file flags a missing plugin, check Effect > Missing to identify which specific effect is uninstalled or incorrectly named.
