Before modifying settings on your server, please consult your firm's qualified IT professional.

You intend to run the CS application in a terminal server environment but are not properly licensed. 

In this scenario, you must purchase a terminal server license for the CS application to run in Terminal Services or Remote Desktop Services. Please contact your CS Sales representative if you require a terminal server license.

You have purchased Terminal Server licenses, but have not yet downloaded new license files. 

When licenses are upgraded after the program is already installed, a new copy of the licenses must be downloaded in the wake of the upgrade.

You do not use Terminal Services or intend to run the CS application in a terminal server environment.
