Web deactivations are designed to deactivate a computer that is no longer accessible. You are allowed as many "legal" activations and deactivations as you need. There are no limitations whatsoever. However, since the web deactivation cannot properly validate the computer is no longer in use, only one license can be forcibly deactivated from the website every 10 days. If for some reason your office building burns down and you really cannot access your computer for a true deactivation for multiple computers, we will be more than happy to manually deactivate your license manually so you can reactivate on your new computers. Go through the normal deactivation process to move a license from computer to computer.
