The installation of BusinessObjects XI Integration for SAP Solution cannot continue because WACS has been installed with Business Objects Enterprise

This is the issue i encountered during installation of the BO Integration Kit. SAP note 1408550 will solve the issue.
Resolution :

To solve this issue, uninstall the Web Application Container Server (WACS)

- From the Control Panel select Add or Remove Programs
- Select the installation of Business Objects xi 3.1 and click Change
- Within the Installer select Modify
- Select Server Components > Web Application Container Server
- Choose the option : The entire Feature will be unavailable
- Click Next

Cause :

The Web Application Container Server (WACS) is not a supported application server for the Business Objects XI Integration for SAP Solutions.

To use .NET InfoView on IIS together with BusinessObjects XI Integration for SAP Solutions, you are still required to install backend applications such as CMCor Web Services on a supported Java application server.
