I forgot my license key

Answer:

The license key takes the form of 79F7-C8-XX-XX-XXXX, and, we send the license key in a separate email at the time of your NumXL purchase or, for trial users, with your 14-day free trial request email.

Furthermore, you may use the NumXL License manager to look up your license key using your email address.

1. Launch NumXL license manager from the start menu.
   
2. Click on the Lookup key button.
   
3. Enter your name and email address.
   
4. A confirmation message pops up.
   
5. After a few minutes, you should receive an email with the license key associated with the email address. Please, check your inbox and/or spam folders.
