If you do not wish to install all the Chameleon components, you can omit the ones you do not want by invoking some simple command line switches. You can view a list of valid command line switches by typing chameleon_windows.exe /? at a command prompt as shown below:

chameleon_windows.exe /?

A dialog window appears, displaying all of the valid command line switches.

Valid Command Line Switches

	Even if you do not want to install all of the Chameleon components, it is still a good idea to install some helpful diagnostic tools like the Message Browser, HL7 Listener and HL7 Simulator to assist with on-site support and troubleshooting.

An example of a silent install using the valid command line switches is shown below. The code below installs Chameleon, diagnostic tools (HL7 Listener/Simulator and Message Browser) and Chameleon runtime components.

chameleon_windows.exe /S /TOOLS=0 /STUBCODE=0 /EXAMPLES=0]

Note that deselecting all installer components does not result in an empty installation since the Chameleon runtime components will always be installed.
