The Web Suite 20xx installation fails when the default web site is set to any port other than 80.
Your default web site must be configured to port 80 prior to any installation of Web Suite. This applies to the full installation or any service pack.
To configure the default IIS web site to use port 80:
1. On the Windows desktop, click Start>Administrative Tools>Internet Information Services (IIS) Manager.
2. In Internet Information Services (IIS) Manager, on the Connections pane, expand the computer name and go to Sites>Default Web Site.
3. Under the Actions pane>Edit Site, click Bindings.
4. In the Site Bindings dialog, click the 'http' entry and then Edit.
5. In the Edit Site Binding dialog, enter 80 as the Port and then click OK.
6. Back on the Site Bindings dialog, click Close.
7. Under the Actions pane>Manage Web Site, click Stop and then Start.
