Wordpress Theme does not work without Purchase code

I donwloaded this:

Item Title: One Page Landing Page WordPress Theme
Item URL: One Page Landing Page WordPress Theme by Ninetheme on Envato Elements
Author Username: Ninetheme
Licensee: xxxxxx
Registered Project Name: xxxxxx
License Date: March 26th, 2021
Item License Code: K6xxxxxxxxx

After install it requires activation, which is not possible with Item License Code

How do I get it to run?


Please contact your purchased theme author, theme author will assist you.

How to contact an author to get support or for any technical query:


The theme you have purchased is from Elements as well as the purchase code.
To make the theme run properly, you will need to purchase it probably from ThemeForest to get the license
