For each licensed copy of Adobe® After Effects® software, you can activate and use one copy of the full version of the application on one computer. You can also install additional copies on additional computers to use as After Effects render engines, which assist with network rendering. You install render engines in the same manner as the full version of the application, but you do not activate them. You run the render engine using the Adobe After Effects Render Engine shortcut in the Adobe After Effects CS3 folder.
