When Prinergy is running on Windows Server 2012 or 2016 with RSS enabled, PLA is not able to retrieve the license information from Prinergy. It is also possible after restarting the Prinergy server, the Prinergy Floating License Manager is not yet running. To resolve, find the DefaultUser.properties file in the LayoutAutomation\server\WEB-INF\classes folder on your Prinergy server. Open the file in a text editor and add a preference named LicenseServer=<IP Address of the Prinergy Server> substituting the actual IP address. For example, LicenseServer=192.168.0.190
