Multi-threaded Robust Server that runs as standard Windows Service

Our code was never part of a desktop terminal emulator; from the beginning it was finely honed to run at maximum speed in a server environment. This means that Inventu Viewer+ can support more concurrent sessions on a given server configuration than any other web terminal emulation solution.

Comprehensive .NET API Library

Applications that utilize the Viewer+ Emulation Service, such as the FVTerm Fast View Terminal Emulator Web Application, do so with the Viewer+ ViewerLib .NET Application Programming Interface.

By the use of shared memory and native Windows Synchronization objects, the performance of the API through all ranges of application challenges is unsurpassed.

The functionality and proven performance of the API has been strengthened through almost two decades of directly developing customer applications with the API by Inventu as well as creating application generators that leverage its power.

Microsoft Management Console Snap-In

This standard Windows Administration Application can be run stand-alone or added to an Administrator's MMC environment to provide integrated runtime management of the Viewer+ Emulation service. It is an excellent tool for both Administrators and HelpDesk personnel as users can be assisted directly through the use of the built-in terminal emulator.

It provides the ability to configure one or more Viewer+ server clusters as well as individual servers so that from one view, multiple Viewer+ Servers can be monitored and managed. View options include the ability to search for a user or view literally thousands of session status' using a tile view.

Full Function Administration Application

This application provides similar functionality to the MMC Snap-In but has more comprehensive configuration capabilities. Server-specific properties are created and managed with the Administration Application, while it is now recommended that all other configuration be performed with the Profiles Framework Configurator.

In addition, easy access to the Trace Viewer and original Screen Recording App is provided with menu options

In addition, it provides convenient menu items for launching various utilities as well as starting, stopping and restarting the service. Starting with the 2020 Inventu Viewer+ setups, the Taskbar Notifier no longer requires Administrator mode and will automatically start with a system restart or power cycle.
