A: Yes, you can. Our online store has been updated to handle this automatically. This is how you can do it:
Go to our upgrade page on our website:
Enter your current license key into the available text field and press the validate button. This will bring you to your available upgrade options. Scroll down to the “Add a Computer” section, and press “Buy” to proceed with the purchase (See screenshots below). After purchasing, you will receive an email confirming that the computer has been added to your license. You can then use your existing license key on a third computer.
