Explaindio Elements activation is divided in two parts. 

Part 1: Activating Explaindio Elements on your computer.

Part 2: Validating your Account inside Explaindio Elements software.

Part 1:

Activating Explaindio Elements on your computer:

a. When you Launch Explaindio Elements for the first time you’d be asked to enter your License Code

There are 2 places where you can get your License Code:

In your Email:
Once you subscribe you will receive an email from us with a subject saying New License Generated. You’d find your Application License Key in the email. However, don't forget to check your Spam or Junk Email Folder if you couldn't find an email in your Inbox.

On your EXPLAINDIO Membership Page:
Login to your EXPLAINDIO Membership Account in this URL: https://account.explaindio.com or by clicking here. On your Dashboard click on Licenses. And, you will find your License Code (License Key) by the application name.

b. Select and copy your License Key from your Email or from your Explaindio Membership area. Paste it in Explaindio Elements software in the box for License Code and click Activate. You will see the software will check the license validity and activate your software. 

Part 2: 

Validating your Account inside Explaindio Elements software:

Go To Settings. Enter your Explaindio Member Account Username And Password Inside Settings of your Explaindio Elements Software then close Settings. (This would be the same username and password you use to login to your Explaindio Membership area here: https://account.explaindio.com)
