Chameleon's installer makes it easy to upgrade your current Chameleon-only installation. This section shows you how to safely upgrade your Chameleon installation in Windows. Before upgrading your system in your production environment, iNTERFACEWARE strongly recommends performing the upgrade on a test machine first.

For information about upgrading both Iguana and Chameleon, see Upgrading Iguana in Windows.

	Important Changes Before upgrading your current installation, please make note of the following changes: The "legacy" LLP networking components (found in versions prior to 3.3.146) have been re-added to the standard installation starting in version 4.5.1 to help customers with older C++ and Java applications still in circulation. This makes it easier for customers who have significant legacy code bases to upgrade to the latest version of Chameleon. However, since these components are considered "legacy" and have since been replaced with new LLP networking components (found in versions 3.3.146 and above), iNTERFACEWARE cannot offer support for these components should you encounter problems with your applications. To avoid any issues, you should plan to migrate to the new components in the near future. If you are creating a new application, or upgrading your "legacy" application, use the networking components described in Chameleon Networking Components.

To upgrade Chameleon:

• Back up any existing VMD files stored in the Chameleon installation directory. Ideally, you should probably back up your VMD files periodically as a routine backup anyway.

• Save a copy of the prior release in a temporary directory, just in case you want to revert back to it after performing the upgrade. You can obtain a copy of the previous release from: http://dl.interfaceware.com/chameleon/.

• In your web browser's address bar, go to http://www.interfaceware.com/chameleon_download.html.

• On the Chameleon Download page, click either the exe or zip link. In this example the Chameleon executable is being downloaded.

• Double-click the ChameleonSetup.exe file on your desktop. The iNTERFACEWARE Chameleon Setup Wizard appears.

• Click Next. The Setup Wizard detects than an installation of Chameleon has been found. The installer automatically uninstalls and reinstalls Chameleon. Please note that this process saves your key registration information, meaning you do not have to register Chameleon again.
