Trapcode Form comes packaged in the Trapcode Suite installer. Note that this does not mean you need to install the entire suite to use Trapcode Form, just that the installer has the ability to install both Trapcode Form as well as other products within the Trapcode suite, depending on what you select during the installation process.
This page explains how to install the Trapcode product you purchased and/or other Trapcode products in Trial mode.
Before beginning:
The Trapcode Suite installer will provide general host and OS specifications it can run in. Trapcode Form runs inside the latest versions of After Effects. For the latest compatibility information, please check www.redgiantsoftware.com/support/compatibility/. You will need to Agree to the EULA to continue with installation.
The installer will list all of the products in the Trapcode Suite for installation, along with checks next to which ones it's ready to install. Select or Deselect whichever products you want to install on this screen.
The installer is ready to install plugins and files onto your setup that will be accessible by all users on your system, and it will need to ensure you have administrative privileges before it's able to do so. Once this is done, the installer will install all of the necessary files!
The installer now displays a confirmation that the products were installed. You will want to select Enter Licensing Info... to input your serial number and register whichever products you'd purchased, otherwise they will remain in Trial Mode.
From here you can optionally click Resources... which will take you to FAQs, User Guides (including this one), and Tutorials for various Trapcode Products. What's New heads to an overview of what's been added in the latest update. And Close lets you exit the installer and head to your plugins within their compatible host applications!
