To activate your license, you must have administrator privileges. Ensure you are logged in as the Administrator.

You need to set UAC (User Account Control) off or Log in as Administrator, or run the installation as Administrator and then try again.

On machines where the user has limited access permissions, it is necessary to run the Activation as an Administrator. This is achieved by right-clicking the software icon and selecting Run as Administrator from the list of options. If these Activation is run without administrator-level privileges, user modifications may not be saved correctly.
