Whether you are activating for the first time or renewing your license, this guide will help you gain access to the full MASS software

In order to be able to activate MASS, you need to know your serial number which starts with the letter B and is 31 characters long.

You can find it on your MASS website dashboard (link will open in a new tab). Don’t have a serial number? You can purchase yours on the MASS website store by clicking here.

If you have an internet connection, the easiest way to activate is Online

If you’ve already tried to activate online and it didn’t work, click here. If you don’t have any internet connection at all, click here.

No internet? No Problem!

We’ve always had the option of activating offline because not every computer has internet and even for the ones that do, there can be problems that come along. Click here to jump to the Offline Activation guide. Please be advised that this involves contacting MASS technical support so activation may not be possible outside of regular business hours.
