Flynet Viewer Installation V2

This course covers the installation process for both Flynet Viewer Server and Flynet Viewer Studio

Flynet Viewer Server V2

Install Flynet Viewer Server

The Flynet Viewer Server contains the core Flynet Viewer Emulation Service. This is the service that manages all sessions, screen protocols, and supports the base Flynet Viewer API. All Flynet Viewer solutions are built upon this core service and API.

In addition to this, the Server also includes the Terminal in a Browser*, as well as a whole assortment of other useful tools.

*Subject to licence.

Installing Flynet Viewer Server

Now we will look at installing Flynet Viewer, and the files that are installed.

If you don't have the installer file it can be downloaded here:

64-bit Download


32-bit Download

If you are not sure which you should use, try the 64-bit version first.


The Flynet Viewer Server installer automatically activates Windows roles and features, or prompts you to download components if required.

Flynet Viewer Server installer will scan the local machine, looking for missing components. If any are missing, the installer will prompt to install them.

Starting The Installer

The Flynet Viewer Server is a normal Windows wizard style installer.

Your start the process by double-clicking on the installer file. Please note that there are 32-bit and 64-bit version of Flynet Viewer Server. Please make sure you are using the correct installer for your target machine.

The installer will scan and offer to install any missing components, as described on the previous page. An older Windows system may offer a URL to download Microsoft .NET Framework 4.x.

You are asked to review and agree to the Licence Agreement.

Target Host

Next you provide the target host IP and port for the first host that you wish to set up with Flynet Viewer.

Connecting to hosts using SSL/TLS and SSH will need further configuration after the installer has completed.

Host Terminal Emulation Type

Here we have the choice of three terminal type families.

  • Select TN3270 for IBM Mainframe.
  • Select TN5250 for IBM AS/400 or iSeries.
  • Select VT100/VT220/SCO-ANSI/ViewPoint/Wyse for the Character Mode hosts. This includes VT, xterm, Wyse, ViewPoint, MultiValue, and more.

You will then see the standard Select Destination Folder steps, and a then Flynet Viewer will install.

End of Installation

Congratulations, you have now successfully installed Flynet View Server. Next, we will cover details about the installed file locations and Applications

What version of Windows is Flynet Viewer Server available ?

Installed File Locations and Applications

Files and Components

We will start off looking at the locations of the files, and what their purpose is.

Secondly, we'll have a high-level look at the installed applications and components.

File Locations

Default Flynet Viewer file locations are:C:\Program Files\flynet\viewer

The main folder for Flynet Viewer. We will look into this folder in more depth on the next page.


The Flynet Viewer Web Terminal Emulation application.


Flynet Viewer API files stored in the Microsoft .NET GAC.


Standard settings and storage for web applications. This is used by the Flynet Viewer Web Terminal Emulation application.

The flynet\viewer Folder

The flynet\viewer folder contains the following files and folders


The Admin Console and Trace Viewer.


The binary folder contains the server installations executable files. These include the Flynet Viewer core emulation service (FlyServer.exe), the Flynet Viewer System Tray Control (SCControl.exe) and the Simulated Host (SimHost.exe).

bin\FW4.0 and bin\Win32

These sub folders contain the Flynet Viewer APIs as library and assembly files.


The code-page translations files, such as US/Canada, UK etc.


Location of XML definition files used for high-speed recognition of screens.


Default location for log files.


The standard Microsoft Management Console Snap-In for Flynet Viewer.


The location of the Recorder used for capture screens for development.


The default location for recordings created by the Recorder.


The location of simulated host scripts.


Configuration files for SSH connections for UNIX-style hosts.


Configuration for SSL / TLS connections for iSeries and Mainframe.

Applications and Components


The Flynet Viewer folder on the Start Menu gives access to administrative and development tools.

End of Lesson

Next we will look at adding a "Host Definition" to Flynet Viewer Server

Pick the correct answer

  • This is correct
  • This is Wrong

Add a Host Definition to Flynet Viewer Server

An activity that adds the host that we're going to use during this course.

Open the Flynet Viewer Admin Console


It is important that you follow these steps exactly. The host definition will be used later in this course. If you have set it up differently, the guidance may not make sense, and you may have to go back and update the settings to what is here.


  1. Open the Admin Console: Windows Start Menu -> All Programs -> Flynet Viewer -> Admin Console.

Add a Host Definition



  1. Click on the blue right-arrow (action icon) next to 'Hosts'.
  2. Click 'Add a Host Definition'.

*The location and value of text that can be found on the screen that indicates the host has reached a good connection state.

Host Settings for Activity

Apply the Settings



Press the [Apply] button at the bottom left of the Service Settings window.

Press [Cancel] button on the 'Flynet Viewer Administration' pop-up. This is for setting up the Flynet Viewer Terminal in a Browser, which we are not going to configure in this course.

End of Activity and Section

Congratulations, you have reached the end of this section. The Next section will cover the "Insure Simulated Host" - This will simulate a connection to a mainframe hosted application and allow you to interact with it.

The Insure Simulated Host V2

The Insure Simulated Host

In this topic, we learn how to use the Flynet Viewer Simulated Host, and the Insure script. The Insure script simulates an insurance application running on a mainframe. We are going to use this simulated mainframe throughout our training.

The Simulated Host is useful for safely designing and developing Flynet Viewer solutions while offline from a host. It is also useful for training and testing. The Simulated Host runs as a Windows Service, and by default listens on the standard Telnet port. You can script TN3270 and TN5250 applications, and play back captures of other terminal types.

Controlling Flynet Viewer Simulated Host


The Flynet Viewer Simulated Host runs as a Windows Service. It can found in the normal Windows Service admin tool running under the (legacy) name of 'Flynet Screen Simulator'.

The Flynet Viewer Simulated Host in the Window Service admin tool.

The more common way to manage the Simulated Host is via the red 'S' icon in the system tray next to the clock. Using this Taskbar Control you can start, stop and restart the service.

The Flynet Viewer Simulated Host Taskbar Control.

Configuring the Flynet Viewer Simulated Host


By right-clicking the red S Taskbar Control, you can access the Settings menu option.

The Flynet Viewer Simulated Host Taskbar Control.

After selecting the Settings menu-item, you will be presented with the Settings dialog.

The Flynet Viewer Simulated Host Taskbar Control Settings Dialog.

The Active Script is the path and filename of the script or trace that the Simulated Host is currently pointing at. A script represents a simple set of programmed screen actions, and a trace is a capture of a host. A script can contain simple intelligence. A trace has no scripting. With a trace, the Simulated Host blindly plays back what was captured from the live host.

Pressing [OK] updates the Active Script that the Host Simulator is pointing at. The [Compile] buttons prompts the Simulated Host to read the Active Script, and make it live within the service. [Cancel] leaves the dialog without making a change.

Every time you change a script, you must Compile it. In addition to there being a [Compile] button on the Settings dialog, there is also a Compile menu item directly on the Simulated Host Taskbar Control.

Flynet Viewer Simulated Host Settings in the Registry


Similar to the settings in the Admin Console, the settings for the Simulated Host are available in the Windows Registry. You can find the setting at HKEY_LOCAL_MACHINE\SOFTWARE\Flynet\Screen Simulator.

You must use the Compile action if you change the Active Script. If you change any other setting, you must restart the Simulated Host service.
