通过检查注册表来了解是否已安装IIS [英] Find out if IIS is installed by examining the Registry

问题描述

我有一个innosetup安装程序，需要创建IIS虚拟目录.为了创建虚拟目录，必须启用IIS管理服务.

I have an innosetup installer that needs to create an IIS Virtual Directory. In order to create the virtual directory, IIS Management Service must be enabled.

如何检查启用了哪些Windows功能?最好的解决方案是检查注册表设置，但是通过innosetup可以使用的其他方法也可以.

How do I check which Windows Features are enabled? The best solution would be to check a registry setting, but other methods that are possible via innosetup are fine.

该解决方案应与XP，Vista，Win7，Win2003服务器和Win2008服务器(32位和64位)一起使用.

The solution should work with XP, Vista, Win7, Win2003 server and Win2008 server (32 and 64 bit).

推荐答案

我不知道如何直接判断安装了哪些功能. 在IIS的特定情况下，您可以通过查找以下注册表项来识别:

I don't know offhand how to generically tell which features are installed. In the specific case of IIS, you can tell by looking for this registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetStp

如果存在该密钥，则安装

IIS.如果缺少密钥，则说明未安装IIS.

IIS is installed if that key exists. If the key is missing, IIS is not installed.

此处有更多详细信息.
