I am VERY new to installing any type of server program and to running any opensource type software in general. I am running Windows Server 2008R2. I want to install Collective Access to run locally only on my Intranet at home. So my host is localhost I sucessfully installed PHP and MYSQL. I installed CA in this directory C:/inetpub/wwwroot/collectiveaccess. 1st. I do not want to send mail through collective access. Will it install without all the email information? Can I comment those requirements out in the global config and setup.php file? 2nd I am getting the error. Configuration file is missing for hostname 'localhost' this is what I have in the set up file: define("CA_WEB_ROOT_DIR", "c:inetpub/wwwroot"); define("CA_URL_ROOT", "/collectiveaccess"); define("CA_SITE_HOSTNAME", "localhost"); define("CA_DB_HOST", 'localhost');
