Upgrading Your License

When you purchase a perpetual license, you receive the current version of the software. As long as your maintenance plan remains active, you are entitled to all new versions and updates we release.

If your maintenance expires and you later decide to upgrade to a newer version, a reinstatement (upgrade) fee will apply. Expired licenses may be renewed within one year of the expiration date. After that period, a new license purchase may be required.

These upgrade and reinstatement policies do not apply to subscription licenses. Subscription licenses must simply be renewed to maintain access. If a subscription is allowed to expire, it may be repurchased later at the then-current subscription rate.
