我想在网页中实现自动安装一个ocx控件（安装了office后都会出现在c:\windows\system32下面），使用如下语句：
<OBJECT ID="MS" CLASSID="CLSID:86CF1D34-0C5F-11D2-A9FC-0000F8754DA1" style="display=none" CODEBASE="mscomct2.ocx#Version=6,0,0,0"></OBJECT>

结果安装时不管本机上是否已经注册过该控件，都重新安装。安装到了C:\WINDOWS\Downloaded Program Files下面，每次重新安装时大小都会累计。

请教如何能判断已经安装了就不再安装？
