Hi Vimal,
please check if there is a licenseKey.xml in the IntegrationServer/instances/default/config directory.
Was this instance working already or did it fail directly from the beginning after installation?
In previous versions IS would start even with invalid or expired license for 30 minutes so you can point it to a valid license file via IS Admin UI → Settings navigation.
Is there a more detailed message in the server.log why IS considers the license file invalid?
Regards,
Holger
