SandyI may be way off beam here but I presume, given the fact that your app is running on a Nexus tablet, that it is a 17.1 web application.I don't think that you need a 'client' licence as such but need to make your IIS server running Webapp 17.1 'visible' to your Nexus (VPN, static IP etc.). This would allow you to test your setup.Maybe SWM can adviseEric
