All Project Professional 2013 clients that have not been updated to the specified cumulative update or a newer version will be unable to connect. For example, if you recently updated both Project Server 2013 and Project Professional 2013 to the same cumulative update, you can verify that all clients that connect to the server are at least at this level by entering the build number. This setting lets you ensure that Project Professional client connections to the server are all at a required base level.

To access and configure this setting, you must be a farm administrator.

Project Professional Versions is a part of the Additional Server Settings in the Operational Policies section of Project Server 2013 Server Settings. Summary: Use the Project Professional Versions setting to define which builds of Project Professional 2013 can connect to Project Server 2013.
