The Activation too can be used to remotely update the license information on your PST license key (dongle).
Your PST license key must be attached to the machine to activate a product.
NOTE: You will need internet access to use the Activation Tool.
Go to Help>Activation Tool to launch the Activation Tool.

Contact PST to purchase new products and provide them with your serial number. The serial number is the 3rd text box in the product code.
In this case it is 972766734. Once you have purchased your new product, it is a simple process to activate the license for it.
Click the 'Update' button to load the newest set of products into the 'Product to activate' drop down list.
Select the product to activate from the list.
Click the 'Activate' button.
You will receive a confirmation message in the status bar of the Activation Tool.
If the product cannot be activated or if an error occurs a message will be shown in the status bar also. Contact PST in the case of an error.
If you do not have a valid license for EZ-Scan you will see DEMO in the EZ-Scan title bar. Once your license is activated the DEMO caption will no longer appear and the software will be out of Demo mode.
