# Starting the Application (Network Module) | Top Previous Next

If you have the network module activated the product starts slightly differently to the start-up of the stand-alone version. If you do not have the network module activated then skip this section. The first step in the start-up for a network user is a simple Logon screen: - Select your username from the list and enter the password given to you by the system administrator. - Select from the available licenses the calculation functionality you will need. - Press the OK button and the application will start up. In the below example the user 'Administrator' will be using 3 modules from a total pool. (Note, the default 'Administrator' password is: PSFF) The next user to log on will see the following Logon dialog. Notice that there are now less modules available as Liquid, Gas, and Two-Phase modules were taken by the 'Administrator' who logged on first.
