Exchange Server 2010 setup cannot continue installation on the Windows Server 2008-or Windows Server 2008 R2-based computer because the Windows Process Activation Service - Process Model feature is not installed on the server.

The Windows Process Activation Service generalizes the Internet Information Services (IIS) process model, removing the dependency on HTTP. All the features of IIS that were previously available only to HTTP applications are now available to applications hosting Windows Communication Foundation (WCF) services, by using non-HTTP protocols. IIS 7.0 also uses Windows Process Activation Service for message-based activation over HTTP.

The Process Model hosts Web and WCF services. Introduced in IIS 6.0, the Process Model is a new architecture that features rapid failure protection, health monitoring, and recycling.

To resolve this issue, install the Windows Process Activation Service - Process Model feature on this server and then rerun Exchange 2010 setup.

Install the Windows Process Activation Service - Process Model feature by using the Server Manager tool
  1. Click Start, click Administrative Tools and then Server Manager.

  2. In the left navigation pane, right-click Features, and then click Add Features.

  3. On the Select Features pane, scroll down to Windows Process Activation Service.

  4. Select the check boxes for Process Model.

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

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