  1. The designer components require access to MCS to retrieve or publish data. MCS can be installed on the same computer or on a separate computer.

  2. In Windows environments, the installation process checks for the presence of an existing installation of Tomcat. If an existing installation is present, it is upgraded by the installation process; otherwise, during installation Tomcat v. 4.0.4 is installed automatically.

  3. Host Access Server management components installed on a Windows system cannot coexist with a separate Tomcat v. 4.0.4 installation running as a service on the same server (by default, Tomcat runs as a service). Attempting to run both on a single server produces a service name conflict. If the Tomcat installation is not running as a service, the two installations can coexist.

  4. IIS must be configured to both run on and use port 80.
