Installing Chameleon Silently (Versions Prior to 3.3.173)

	All Chameleon versions prior to 3.3.173 use an installer based on Wise. All subsequent versions utilize an installer based on Nullsoft.

The Chameleon installation program can be run automatically by your own installation program by invoking it with some command line switches:

Chameleon.EXE /s /M=install.txt

The install.txt file is a file you supply which gives the components of Chameleon that you wish to install on your client machine. You may wish to install the entire set of tools on every machine. This file allows you to select just the components that are necessary. The content of the file should be of the form:

COMPONENTS="BCE"
MAINDIR=C:\Program File\Application Install Dir\

The MAINDIR gives the installation directory for Chameleon. Remember not to put quotes around the value for this variable and to have a trailing \ character.

The letters in the COMPONENTS variable stand for different components of Chameleon as documented in this table:

Just select the components required for your application, usually just B and sometimes F and G if you used these components.

It's a smart idea to install some helpful diagnostic tools like the message browser, the HL7 listener, and simulator to assist on site support and troubleshooting.

Make sure that Chameleon is not running any applications which use Chameleon when you run the installation program. Otherwise, a reboot will be required after the install. However, as of version 3.212, performing a silent install will suppress any reboot prompt that may appear at the end of Chameleon's installation procedure. Note that a manual reboot will still be necessary in order to complete the Chameleon installation.

	You can test your implementation by excluding the /s which stands for doing a silent install of Chameleon. The install will run interactively which makes it easier to ensure you have the install variables correctly set.

Removing Shortcuts

It's very easy to not have shortcuts to the Chameleon GUI etc. accessible from the desktop. Just write a little bit of logic in your setup program to remove the shortcuts created by the Chameleon setup.
