can you reset my page please

I didn't want word press, I wanted Joomla but Joomla didn't like wordpress so I though what the heck and deleted the files. Now joomla won't install because some root file is missing.
Can an admin reset the pages please so I can install joomla or tell me how to do it.

You have to remove Wordpress from your website control panel. Click on the app name in your dashboard to access the application management section and choose "remove application". After you can install Joomla.
