Software Maintenance Service

For Gaaiho PDF Perpetual License


The Software Maintenance Services (henceforth, SMS) provides an economical way to receive product upgrades and get technical support. It does not only cover all updates, upgrades and technical support during the timeframe selected (starting from the purchase date), but is also a cost-effective way to upgrade product instead of buying new license, usually released on an annual basis. You may continue uninterrupted service in subsequent years by renewing your SMS subscription.

  • Definition on Update and Upgrade Zeon's definition of "upgrade" means a rise in the major version number, e.g. v6.5 to v7.0, whereas "update" means a rise in the minor version number, e.g. v7.1 to v7.5.
  • Upgrade and Support within SMS Coverage Perpetual license does not have an expiration date. However, free upgrade can only be obtained during the subscribed SMS period and user may go to Gaaiho PDF website and download new version. Priority technical support is also given to the subscribers.
