Web Server Prerequisites

If the server where you want to install Express Server runs IIS 7 or IIS 8, ensure that ISAPI extensions have been installed. If the server where you want to install Express Server runs Apache or another version of IIS, skip to Installation.

ISAPI Extensions for IIS

ISAPI extensions make it possible for server applications like Express Server to access additional IIS functionality. To verify that ISAPI extensions are enabled for IIS, complete the following steps:

1. Click Start, then click Administrative Tools from the right-hand panel and choose Server Manager.

   The Server Manager appears as shown below.

2. If another pane besides the Roles pane is displayed, select Roles in the left-hand navigation pane.
3. Expand the Roles Summary box in the large pane at right if it has not already been expanded.

4. In the Web Server (IIS) section, click Role Services to see whether ISAPI extensions are installed.

Installing ISAPI Extensions

If ISAPI extensions have not been installed, complete the following steps:

1. If the Server Manager is not already open, click Start, then click Administrative Tools from the right-hand panel and choose Server Manager. The Server Manager appears.

2. Click Add Role Services among the right-hand links. The Select Role Services dialog appears as shown below.

   

3. Under Application Development, select the ISAPI Extensions checkbox.
4. Click Next, then click Install.
