1. Login to your Capture One Profile at www.captureone.com. Click on "Login"
2. Click on "Software License"
3. Choose your Capture One User Product to display your license key.
Choose "Reset All Activations." Please note that deactivation affects all installations with the license code!
The "activations left" will now read "3" for Capture One Pro 9 licenses, or read "2" for Capture One Pro (for Sony) licenses, or for any prior version of Capture One Pro.
You will now be able to activate Capture One on a new machine. This will remove the activation from all currently activated machines.
For example If you had Capture One activated on two machines and are replacing only one of them, you will have to activate the new computer as well as the other computer where Capture One was already in use and activated. Since this process removes all Capture One activations.
You may also reset each activation individually, with "Reset Activation." This will only reset 1 activation at a time.
