For a purchase through the current checkout
Current-checkout activation uses the purchase email and the license key provided with it. The help page describes opening the panel, right-clicking an empty area and choosing Settings → License to enter those details.
If you have just paid, allow time for payment and license confirmation. If activation needs help, send support the receipt or order reference and the exact message from the application. Work from the existing purchase while support helps you resolve it.
- Open the Nook and right-click an empty part of the panel.
- Choose Settings → License.
- Enter the email and key supplied with the current-checkout purchase, then select Activate license.
For a missing key or a device change
Contact support from the email used for the purchase when you need to recover a current license key. For a device-limit question, the help page explains how to release an activated Mac in License settings when it is accessible.
Describe whether you are setting up another Mac, replacing a machine or trying to use the original one again. This gives the request a clear purpose without requiring a long account of unrelated setup steps.
For an earlier-store purchase
Use the dedicated earlier-purchase section of the official help page. It separates lifetime and monthly purchase paths and provides the current contact route for each.
A concise message should include the purchase email, receipt or order reference and what you are trying to do now. Keep the conversation with support@getnotchnook.com so the team can follow the purchase and application details together.
