When upgrading from a version of ExtraView older than 6.2, you must obtain a new activation key from ExtraView support. You will not be able to start the ExtraView application without this new activation key.
When you first log in to ExtraView after restarting Tomcat, you will see the following screen that allows you to upload the new activation key. You can also upload the activation key from the Administration menu, by clicking on the Upload Activation Key function.
Following the successful upload of a valid activation key, you will see a verification screen that displays the details of the key.
