Microsoft® Exchange Server 2010 Setup cannot continue because the required Internet Information Server (IIS) 7 .NET Extensibility component is not installed on the target server.

Before Exchange 2010 can use Windows PowerShell Remoting, the IIS 7 .NET Extensibility component must be installed on the target server.

To address this error, use Server Manager to install the IIS 7 .NET Extensibility component on this server and then rerun Exchange 2010 setup.

Install the IIS 7 .NET Extensibility component in Windows Server 2008 or in Windows Server 2008 R2 by using the Server Manager tool
  1. Click Start, click Administrative Tools and then Server Manager.

  2. In the left navigation pane, expand Roles, and then right-click Web Server (IIS) and select Add Role Services.

  3. On the Select Role Services pane, scroll down to Application Development.

  4. Select the check box under .NET Extensibility.

  5. Click Next from the Select Role Services pane, and then click Install at the Confirm Installations Selections pane.

  6. Click Close to exit the Add Role Services wizard.
