For IIS7, check the following Registry Key:
对于 IIS7，请检查以下注册表项：
HKEY_LOCAL_MACHINE\Software\Microsoft\InetStp\Components\
HKEY_LOCAL_MACHINE\Software\Microsoft\InetStp\Components\
For the following components:
对于以下组件：
- Process Model - ProcessModel
- .NET Environment - NetFxEnvironment
- Configuration APIs - WASConfigurationAPI
- 流程模型 - 流程模型
- .NET 环境 - NetFxEnvironment
- 配置 API - WASConfigurationAPI
From this page: http://learn.iis.net/page.aspx/135/discover-installed-components/
从这个页面：http: //learn.iis.net/page.aspx/135/discover-installed-components/
UPDATE:Since the above is true even when the components are not installed, try running this command from the command line:
更新：由于即使未安装组件，上述情况也是如此，请尝试从命令行运行此命令：
sc query nettcpactivator
sc 查询 nettcpactivator
If the service is stopped or does not exist, the WCF Non-HTTP Activation components are likely not installed. To install them, run this command:
如果该服务已停止或不存在，则可能未安装 WCF 非 HTTP 激活组件。要安装它们，请运行以下命令：
pkgmgr /iu: WCF-NonHTTP-Activation
pkgmgr /iu: WCF-NonHTTP-Activation

For IIS8 with Windows Server 2012 (and probably Windows 8), you can check this registry key (for .NET 4.5)
对于带有 Windows Server 2012（可能还有 Windows 8）的 IIS8，您可以检查此注册表项（对于 .NET 4.5）
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ServerManager\ServicingStorage\ServerComponentCache\NET-WCF-HTTP-Activation45\InstallState
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ServerManager\ServicingStorage\ServerComponentCache\NET-WCF-HTTP-Activation45\InstallState
zero means not installed, and 1 means installed.
零表示未安装，1 表示已安装。

You also can use PowerShell to enable WCF Http/Non-Http Activation components:
您还可以使用 PowerShell 启用 WCF Http/Non-Http 激活组件：
Import-Module ServerManager
Add-WindowsFeature NET-HTTP-Activation,NET-Non-HTTP-Activ
This way you do not have to mess up with Windows Registry. For more info about adding Windows feature with PowerShell: http://technet.microsoft.com/en-us/library/cc732263.aspx#BKMK_powershell
这样您就不必弄乱 Windows 注册表。有关使用 PowerShell 添加 Windows 功能的更多信息：http: //technet.microsoft.com/en-us/library/cc732263.aspx#BKMK_powershell

You should probably use the Get-WindowsFeature powershell commandlet. You can check the existence on Server 2012 of .NET Framework 4.5 WCF Services for HTTP Activation by calling:
您可能应该使用 Get-WindowsFeature powershell commandlet。您可以通过调用以下方法检查 .NET Framework 4.5 WCF Services for HTTP Activation 在 Server 2012 上是否存在：
$wcfActivationFeature = Get-WindowsFeature -name NET-WCF-HTTP-Activation45
$wcfActivationFeature.Installed

The registry key for HTTP activation is:
HTTP 激活的注册表项是：
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup\Windows Communication Foundation\HTTPActivation
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup\Windows Communication Foundation\HTTPActivation
, and for non-HTTPactivation is checking whether the service NetTcpActivationor NetPipeActivatorexist on the machine and are running.
以及用于non-HTTP激活被检查是否该服务NetTcpActivation或NetPipeActivator存在的机器上，并且正在运行。
