thinkphp配置时一直出现问题，怎么才能成功啊？

我的代码是<?php
define('THINK_PATH','../ThinkPHP');
define('APP_NAME','php100');
define('APP_PATH','.');

require(THINK_PATH.'/ThinkPHP.php');

$App=new App();
$App->run();

?>
错误提示是 Warning: require(../ThinkPHP//ThinkPHP.php): failed to open stream: No such file or directory in C:\wamp\www\php100\index.php on line 6
到底该怎么改？求大神告知。十分谢谢！搞了二天了。头疼

我的thinkphp版本是3.2.3。
