In case you are changing your computer or your current/old computer ran into a failure or if you are simply re-installing the software, you need to deactivate your license key first. Then you can use the same license key to activate the software on your new computer or activate it after reinstalling the OS or software itself.
There are 2 places from where you can deactivate your license key from your computer:
1. From the software interface:
If your computer and the software is still functional and you have access to your current from which you want to deactivate the license key or, you are doing a re-install, simply open up the software once again. Then click Deactivate License on the software interface and click Yes.
2. From your Explaindio Membership Area:
If you don't have access to your old computer or if your OS crashed or simply if you forgot to deactivate the license before re-installing, login to your EXPLAINDIO Membership Account in this URL: https://account.explaindio.com or by clicking here. On your Dashboard click on Licenses. Next to the activated license's activation code you will see a disable link. Click the disable link to disable your license from your currently activated computer. You will see this disable link only when your license is currently active on a computer.
