With the changes to our licensing system this year, the licence activation process is slightly different. Your licence now expires on the 31st of December. You can check the expiration date of your licence by starting Mercury, click Help > About Mercury. In the new window that appears, scroll down until you see your expiration date.

If you are using a node-locked activation key on a machine that is connected to the internet, there is very little required of you. If the expiration date is December 31st 2020, there are a couple of steps to take. First, close and restart Mercury. Your machine will sync with our license server and update your licence details if you have renewed your licence. If your expiration date is still the same, please check with your site contact to determine the status of your renewal. If your expiration date is now 2021 then there is nothing else for you to do. Information on accessing the latest release can be found here.

If you have renewed your licence, your expiration date is December 31st 2020 and your machine is not connected to the internet, then you will need to either connect to the internet and follow the steps above or perform an offline activation using the software activation tool to generate a request.

If you have set up the software to use a local licence server, the activation steps can be found here. Notify your site contact on the need to obtain a new local license server key from us.

Note that it is important to check with your site contact on the renewal status first. If you have followed the steps above and still require assistance, do contact us at
