How to Install After Effects Plugins: Windows & Mac Step-by-Step

Master the manual and installer-based plugin installation workflows across Windows and macOS without crashing After Effects.

Understanding After Effects File Formats Before Installation

Before moving files into system folders, you must understand the distinction between compiled plugins, extendable scripts, and CEP panels. Installing a file in the wrong directory will prevent After Effects from loading it upon startup.

TypeFile ExtensionStandard Destination FolderWhere It Appears in AE
Native Plugin.aex (Win) / .plugin (Mac)/Plug-ins/ or /Common/Plug-ins/7.0/MediaCore/Top Menu > Effect > [Plugin Category]
Script Panel.jsx / .jsxbin/Scripts/ScriptUI Panels/Top Menu > Window > [Script Name]
Extension.zxp / .ccxInstalled via ZXP Installer or Creative CloudTop Menu > Window > Extensions

Installing Native Plugins on Windows (Step-by-Step)

For standalone .aex files downloaded from platforms like PRADUMNA_FX Plugins:

  1. Close After Effects completely. Never drop plugin binaries into system folders while the background AE process is running.
  2. Open Windows File Explorer and navigate to the default versioned plugins folder:
    C:\Program Files\Adobe\Adobe After Effects [Year]\Support Files\Plug-ins\
  3. Create a dedicated folder for the developer (e.g., Plug-ins\PRADUMNA_FX\ or Plug-ins\VideoCopilot\) to keep your directory organized.
  4. Paste the .aex file into this newly created folder.
  5. Relaunch After Effects. Open an existing project, create a new Solid Layer (Ctrl + Y), and check the Effect menu.

Pro-Tip: Using the Shared MediaCore Directory

If you use both Adobe Premiere Pro and After Effects, place compatible video plugins in C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore\. Both NLEs will read the plugin binary without duplicating files on disk.

Installing Native Plugins on macOS (Apple Silicon & Intel)

macOS installations require specific permission handling due to Apple Gatekeeper:

  1. Quit After Effects (Cmd + Q).
  2. Open Finder and press Cmd + Shift + G to open the Go to Folder prompt.
  3. Enter: /Applications/Adobe After Effects [Year]/Plug-ins/
  4. Move your .plugin bundle into the folder. (You will be prompted for your macOS administrator password).
  5. Apple Silicon Gatekeeper Fix: If macOS displays a security prompt saying "Plugin cannot be opened because the developer cannot be verified", open System Settings > Privacy & Security, scroll down, and click Allow Anyway.

Troubleshooting Missing Plugins & Startup Crashes

If a plugin does not appear in your Effect menu after restarting:

  • Check Bit-Depth & Architecture: 32-bit legacy plugins will not load in modern 64-bit After Effects CC releases. Ensure your plugin binary is compiled for 64-bit architecture.
  • Verify Visual C++ Redistributable (Windows): Many plugins require updated Microsoft Visual C++ 2015-2022 runtimes. Install the latest official x64 redistributable package if you receive error (126) The specified module could not be found.
  • Clear the Plugin Cache: Hold Ctrl + Alt + Shift (Win) or Cmd + Option + Shift (Mac) while launching After Effects to force a clean plugin initialization scan.

This usually happens if the file was placed in the wrong folder (such as 'Scripts' instead of 'Plug-ins'), if the plugin is 32-bit instead of 64-bit, or if macOS Gatekeeper blocked the unsigned binary.

Yes, if the plugin supports MediaCore, placing it in 'C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore\' (or macOS equivalent) enables both applications to load the same plugin.
