If you get a License Expiration Error when trying to install a client on a different machine on your network, it's most likely because the application path is not set to the server directory, or that the users do not have the necessary rights.
If it is CSSchdeuler you are having difficulty with, check the shortcut and make sure the target path is correct. If it isn't there, add the server path to the start in setting. eg: s:\centerstage\
You can also click "OK" when CSScheduler gives you the message, select "Stations and Logos" from the tools menu and set the Start in path to the server path.
The last possible issue would be user rights to the server path.
