试一试在 install/index.php 中修改获取uri的方法:
function check_webimroot()
{
global $page, $errors, $webimroot;
$requestUri = '';
if (isset($_SERVER['REQUEST_URI'])) { 
$requestUri = $_SERVER['REQUEST_URI']; 
} else { 
       if (isset($_SERVER['argv'])) { 
                    $requestUri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['argv'][0]; 
       } else { 
                  $requestUri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['QUERY_STRING']; 
        } 
} 
if (!preg_match('/^(.*)\\/install(\\/[^\\/\\\\]*)?$/', $requestUri, $matches)) {
      $errors[] = "Cannot detect application location: $requestUri";
      return false;
   }
   $applocation = $matches[1];
..........
并删除(或修改)package中的此行:  install/index.php 284183ee6d174f239fc92a85a8148771
