Nope! The installer for the demo of Soundtoys 5 and purchased version of Soundtoys 5 are exactly the same. You can either wait for your demo to expire, at which time you'll get an activation window when you try to use our plug-ins, or you could follow these instructions to activate it right away using the iLok License Manager:
1- Launch the iLok License Manager (ILM) and log-in. You should find that in your Applications folder on your computer.
2- Make sure your iLok is plugged into a USB port on your computer, and then make sure it shows in the side bar on the left within the ILM. This step is optional for MicroShift, Little PrimalTap, and Little AlterBoy, and any version 5 products.
3- Find the license for your Soundtoys product in the box on the right side. You may need to click the "Available Licenses" tab at the top of the main window.
4- Drag+drop that license to your iLok tab in the sidebar of the ILM. For MicroShift, Little PrimalTap, and Little AlterBoy, and version 5 products, you can also drag+drop to your computer tab.
If you purchased an individual product instead of the full bundle after running our Soundtoys 5 demo, I would recommend an uninstall/reinstall to get all of the other plug-ins off of your system.
