An upgrade is available from GFI FaxMaker 19 to

Important notes before upgrading

  • Follow these notes and instructions to upgrade your current GFI FaxMaker installation to the latest version while retaining all settings.
  • Upgrade is not reversible; you cannot downgrade to the last version.
  • GFI FaxMaker 20 works with a subscription model, where after the subscription expiration the product stops sending faxes and SMS. A renewal of the subscription is required to resume the service.
  • GFI FaxMaker 19.2 and later only support 64-bit installations. It is not possible to upgrade over a 32-bit instance and a new installation in a supported environment is required. For more information refer to How to move your GFI FaxMaker installation to a different server.
  • Backup the GFI FaxMaker configuration before upgrade. For more information refer to How to backup GFI FaxMaker settings. The backup may be useful to revert configuration when upgrade fails.
  • During upgrade, GFI FaxMaker services and operations are stopped. Ensure that there are no faxes in queue as these are permanently lost during upgrade.
  • Check that you are installing GFI FaxMaker on the machine that meets the system and hardware requirements.
  • Log on as Administrator or use an account with administrative privileges.
  • GFI FaxMaker 19.2 and later offers two types of licensing services:
