  • 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.

  • Support Phases
    • General Support Phase

      The General Support phase starts on the date you purchase the product and lasts for 30 days. During this fixed duration, you are eligible to:

      • One-time free installation or activation help
      • Unlimited e-mail support
      • Free version upgrade (if a new version is released)

      ※ Please also remember to provide your order ID, serial number or valid proof of purchase to our support team at the time of submitting a request.

    • Extended Support Phase

      Extended Support phase becomes effective from the end of the General Support phase and lasts for one year. Extended Support is available primarily through the support website and provides two additional support cases related to:

      • Product download, installation, activation and deactivation
      • Product registration
      • Serial number issues

      ※ Customers can also submit a support ticket online to receive help and workaround for critical issues encountered.

    • End of Support Phase

      Products supported are limited to the current and previous major version only. “Current version” stands for the latest major version of software available on the Gaaiho PDF website. For instance, if the latest version is 6.0, version 4.0 and below are not supported.

  • Outside the General Support Phase and without SMS Subscription
