In order to enjoy the full features of Umango after the end of your trial period it is important that you activate your software. This process is relatively simple and will require you to acquire an activation key. You can acquire an activation key from your dealer or, if you have been provided a product key, you can activate online.
My Dealer provided me a Product Key: If you have been provided a "product key" then you can activate your software online. The online activation process provides you with the activation key required to enable your software. From the Umango "Gear" menu, press the "Re-Activate License" button. You will then be taken through the activation process and provided your activation key.
My Dealer will Provide me an Activation Key: Your dealer will require your software serial number in order to provide you your activation key. By selecting "Re-Activate" from the Umango "Gear" menu, you will see your serial number displayed. This is the number you will be asked to provide your dealer together with details of your installation.
Important: Licenses and activation keys for Umango are provided on a "per client computer" basis and cannot be used on more than one computer. If you require more than one computer to run Umango then please purchase a second license.
