Figured it out from one of the other help files (took some digging). Apparently this is a fix for Godaddy on Windows servers.
Go to the wp-settings.php file and make sure replace the following text with the edited-out version I have below.
//if ( !extension_loaded(‘mysql’) ) {
// die( ‘Your PHP installation appears to be missing //the MySQL which is required for WordPress.’ );
//}
Re-upload the files and proceed with the install.php step.
