I've never had any success with one-click installers. They can be (and usually are) customized to some extent by each hosting provider. This means you are not using a fresh, clean copy of Joomla. I've lost hours of work trying to troubleshoot a component that would now work, only to discover that my hosting company changed the way Joomla worked when I used their one-click installers.
Just skip it. Download Joomla from joomla.org and install it. You will learn more and have a better Joomla experience.
