Why do I get the message "The curveset MyPressSyncCurveSet.prsync uses features that require and extra license which is not installed. Please contact Esko" when opening a PressSync curve set in Curve Pilot / PressSync 16.1?
Because of IP (Intellectual property) reasons, it was decided to hide the Advanced PressSync Curves settings (which is an unofficial option) as of 16.1 and make them only available for the Print Control Wizard product (starting from Esko Software Platform version 18.0 and newer).
As a consequence, it is not possible anymore to open a PressSync curve set with Advanced PressSync Curves defined and a message (The curveset MyPressSyncCurveSet.prsync uses features that require and extra license which is not installed. Please contact Esko.) will be generated! The Advanced PressSync Curves settings are also not anymore available (even when the environment variable is available) unless you have a license for the Print Control Wizard).
Activate the Curve Pilot Printing Condition product key (when available / purchased)
Upgrade to Curve Pilot 18.0.1 and activate the "Flexible PressSync" option in the preferences
