Hello Bob Stout,
If you are an individual user, you can choose either to purchase a lifetime license for $44.96 or an annual(1-year) license for $33.26.
An annual(1-year) license allows you to use the full version for a whole year and you need to renew a license to use another year.
If you purchase a lifetime license, you don't need to pay an annual fee.
Please refer to the following link for more information.
