Warning: Running ProcessMaker under IIS (Internet Information Services) has not been fully tested. Official support is only provided for the Apache webserver.

Follow these instructions to install ProcessMaker under Microsoft IIS and install PHP and MySQL using the Web Platform Installer.


Note: Any existing web server (WAMP, XAMPP) must be uninstalled completely, since this can cause problems with ports and versions.

Installing IIS, PHP and MySQL

Open the Web Platform Installer (WebPI) and type 'WebMatrix' on the search bar. Mark the following packages for installation:

                <match url='^.*/(.*)$' ignoreCase='true' />
                <action type='Rewrite' url='sysGeneric.php' />

Save the changes and restart the server.
