All licenses feature a one-time charge with absolutely zero recurring fees. The license allows use of the product for an unlimited time, with all updates to the major version included. There are no restrictions on program use or platform type. A license is required for every separate installation, but licenses can be reused and tranferred to other machines. An online account is not required for license activation or program execution.
Purchasing 5 or more licenses in the same tier activates quantity discounts.
