Not that Adobe has done much to prevent this sort of behavior.
Those possibilities come to life with the addition of the Essential Graphics panel which is where editors will interact with these new templates.
Before these new Motion Graphics Templates the After Effects integration was limited to mainly changing the text but this new workflow will enable a lot more customization for the editor as “text, color, size, layout or mood of the motion graphics” will all be editable depending on how the motion graphics artist sets up the template.
This workaround overcomes the Catch 22 that arises because you must launch the software to remove the old serial number, but the expired serial number prevents you from launching the software. Because Photoshop CS4 no longer represents the shipping version of the product, you can't obtain it from Adobe Systems.
If you didn't purchase a Photoshop CS4 license during the shipping lifespan of the product, you may be able to find a sealed or transferable copy on an online auction site. Open a Finder window and navigate to the Library folder at its main level.
You're not alone in your predicament -- or your frustration -- especially if you see this error message the first time you try to start up the program after you install it. Open the "Help" menu and choose "Deactivate." On the deactivation screen, activate the check box for "Erase This Serial Number" and click on the "Deactivate" button. When the program requests a valid serial number partway through the startup process, enter the serial number for a retail version of the software with no expiration date on its license.
