To open the latest version of DW Spectrum Desktop Client

Click on the DW Spectrum 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. If your client version has been auto-updated, there may be other executable files in other folder locations than the following default initial installation locations.


oOpen the Windows Desktop and double-click the DW Spectrum shortcut icon.

oOpen the Windows Start Menu > Programs > Digital Watchdog > DW Spectrum
