Licence Deactivation - Hardware Issue

My hard drive at home has died and I would like to install one of my Unit Pro installations on my laptop, I am unable to return the licence from my machine as it is damaged.

What is the process to revoke a licence?

If your license is part of an organisation you can remove the seat on the website, there are instructions here: https://support.unity3d.com/hc/en-us/articles/209019666

Otherwise you will have to email Unity support and get them to help you: support@unity3d.com
