Hi,

If you receive an "Invalid License" error when activating Studio One 2, It's possible that the version of Studio One you have installed on your system is the 1.0 version of Studio One.

1.0 is a separate software from 2.0. So, if you try activating 1.0 with your 2.0 key, you will receive an error.

Make sure that you have installed Studio One 2.0.

To install 2.0, login to your account (www.presonus.com/registration) >> My Software. Below Studio One 2.0, you'll see a list of downloads. The first downloads in the list are installers for PC and Mac.

Download the appropriate installer, then install. You can then activate using your 2.0 product key.

Thanks and best of luck!
