Hi,

Registrered RobotStudio 5.x subscribers are entitled to use the latest released version of RobotStudio. There should not be a need to use new libraries in old versions.

Please ensure that your RobotStudio installation is legitimately licensed. Your local ABB office can help you to sign a RobotStudio subscription unless you already have one.
