You install standalone licenses on the machine that is running your Vicon application software.

A Standalone license is locked to a specific machine. A combination of the MAC address of one of the network interfaces and an ID from one of the hard disks in the machine is used to create a unique lock code.

> ⚠️ **Important**  
> ⚠️ Before you begin, make sure you have installed your Vicon application software.

**To request**** and activate a Vicon Standalone license:**

1. From the email you received from Vicon Motion Systems with the Subject line **Vicon - Your Entitlement Certificate**, copy the Product Key for the application you want to license.
  :check_mark: **Tip**: Store the Product Key in a safe location as it allows access to your licenses. If you need to grant access to someone else who has permission to use your license(s), forward the email to them.
2. Go to [https://vicon.prod.sentinelcloud.com/customer/login](https://vicon.prod.sentinelcloud.com/customer/login)  (the Sentinel Entitlement Management System).
