To open the latest version of Nx Witness Desktop Client

Click on the Nx Witness shortcut icon on your PC or mobile device interface to launch the Welcome Screen.

If for some reason you need to use an executable file, the applauncher.exe executable is recommended as it launches the newest installed version of the client. In addition, if another executable is used, it is possible that client restart will not work during auto-updates, and restart to compatibility mode and interface language changes may be disabled.

Note that if your client version has been auto-updated there will be other executable files in other folder locations than the following default initial installation locations.

Windows

•From desktop: click on the Nx Witness shortcut icon

•From Start Menu: go to Start –> Programs –> Network Optix –> Nx Witness

•From the installation folder: click on the executable file. The default location is C:\Program Files\Network Optix\Nx Witness\Client\<VERSION>\networkoptix Launcher.exe

On Windows only it is also possible to automatically launch Nx Witness when a computer starts up:

1.Go to Main Menu –> Local Settings -> General tab

2.Check Run Application when PC boots up

3.Click Apply to accept changes, OK to save changes and close the dialog, or Cancel to discard changes.

IMPORTANT: In order to display video and graphics properly, it is important to have the most current video drivers installed. If current video drivers are not installed, a warning will display prompting you to update your installation.

Launching in Configuration Mode

The Nx Witness client detects PC system configuration automatically. If the CPU and/or graphics adapter are insufficient to render all graphics, the client will launch in configuration mode. This mode restricts functionality as follows to limit CPU load and graphics usage:

•Only one video can be viewed at a time

•Notifications are disabled in the client

•Movement of interface elements is disabled
