Eclipse的RCP插件怎么安装

Question

请问大家，我下载了eclipse的RCP插件，用link的形式安装了上去，结果是有些功能得到了体现，有些没有，怎么回事？谢谢！
[b]问题补充：[/b]
我下载了eclipse-RCP-SDK-3.4.2-win32.zip，用link的形式安装了，但是在做扩展的时候，有此属性没有，而用单独的eclipse插件（Eclipse for RCP/Plug-in Developers (176 MB) ）会有。。是什么问题。

我同事，直接下载eclipse-RCP-SDK-3.4.2-win32.zip 覆盖也会有一样的问题。

大家在RCP开发都没有碰到此问题吗？
