To install Iguana 4.0 or any later version, using the automatic installer, on a computer that is running Windows:

• If you do not have a copy of Iguana to install, download it from the iNTERFACEWARE web site. If you have obtained a copy in .zip format, use WinZip or a similar program to uncompress it.
• If you already have a copy of Iguana on your system, ensure that your Iguana server is not running.
• If you have a copy of Chameleon on your system, ensure that it is not running.
• Start the installation program. A welcome screen appears:

	When installing Iguana, do not have the Services window open. When this window is closed, system files can be updated without requiring you to restart your computer.

• Click Next.
• If a previous version of Iguana is installed on your system, you will be asked to uninstall it:

• Click Yes to uninstall the previous version of Iguana. (See Uninstalling Iguana on Windows for details on uninstalling Iguana on Windows.)
• When the License Agreement appears, read the license terms and select the radio button that states that you have accepted the terms of the agreement.

• Click Next. The Choose Additional Components window appears:

• Iguana depends on Chameleon's messaging toolkit. If Chameleon is not already installed on your system, select the Chameleon check box.
• Click Next. The Choose Install Location window appears:

• Type, or browse for, the location in which to install Iguana.
• Click Next. The Choose Chameleon Install Location window appears:

• Type, or browse for, the location in which to install Chameleon.
• Click Next. The Desktop and Start Menu Shortcuts window appears:

• In the Iguana panel of the Desktop and Start Menu Shortcuts window, select the Desktop shortcut text box if you want to add an Iguana shortcut to your desktop.
• Select the Start menu shortcuts text box if you want to add an Iguana shortcut to your Start menu.
• In the Chameleon panel, repeat the above steps to add a Chameleon shortcut to your desktop or Start menu.
• Click Next. A window appears, indicating that installation is taking place:

• If configuration files already exist, you are asked whether you want your new version of Iguana to use them:

• If you click No, the existing files are moved to the oldconfig directory:

• At this point, installation is complete, and a screen appears that enables you to configure your Iguana installation. (This screen does not appear if you are reusing existing Iguana configuration files.)

• In the Specify the web service port for Iguana field, type the web service port that you want to use, or use the default of 6543.
• In the Specify the directory for Iguana logs field, type or browse for the directory in which the Iguana log files are to be located. (See Log Directory Location Tips for tips on how to choose the log directory.)

	By default, logs are stored in the logs subdirectory of the directory in which Iguana is being installed; for example, if you are installing Iguana in C:\Program Files\iNTERFACEWARE\Iguana\, the logs are stored in C:\Program Files\iNTERFACEWARE\Iguana\logs. For best results, define a separate local partition for your log directory instead of using your system partition or C drive.

• Click Next. A screen appears, indicating that setup has completed:

• Select the Open the iNTERFACEWARE Iguana Dashboard check box if you want to start Iguana after installation is complete.
• Click Finish to complete the installation.

	The automatic installer can only be used to install or upgrade one Iguana server. If you plan to install multiple Iguana servers, see the instructions in Installing Iguana Manually for information on how to manually install additional Iguana servers.

	By default, Iguana stores its configuration file in the directory in which Iguana is installed. You can specify the directory that will contain your configuration file. See Specifying the Configuration File Directory for details on how to do this.
