Magento

I am trying to install in local and remote since 1 week, always error (i can’t go to backend, error message during installation, error to manage ecc. ecc.) i don’t understand why is so complicated to install, why is not like wordpress, joomla, drupal, with 5/6 click you are ready to manage your site.
Please make a solution because is not possible all this time to try to learn, Google is full of post that talk about Magento’s error but nodody have a solution, for ex. try to change locahost with 127.0.0.1, ok changed but NOTHING NOTHING NOTHING.
