Error 14004 "The license file is missing"

Error 14004 saying "The license file is missing" occurs when upgrading the Appeon Server.

Cause: This issue only exists in Appeon 6.5.1 for .NET or earlier versions. When there are server instances installed before, the server instances will not be upgraded during the upgrade process.

Solution: Use the Appeon Server Instance Configuration Wizard to delete all installed instances from the Appeon Server and then re-install these instances. See Installation Guide for Appeon for PowerBuilder for detailed instructions.
