### Define Installation Components

Define the components and subcomponents of your installation.

#### Installation Directory

Enter the directory where the __INSTBLE__ software is to be installed.

For new Tomcat installations, the directory must be a new or empty directory. If you enter a path to a new directory, PTC.Setup creates the directory for you.

Note: The default Tomcat installation directories are C:\ptc\tomcat on Windows systems and /opt/ptc/tomcat on UNIX systems.

#### Platforms

Select the types of machines that are to access this installation directory. PTC.Setup detects the hardware platform of your machine and lists that machine type as the default.

#### Components

For the installation of the Apache Tomcat servlet engine, accept the checked Apache Tomcat files component. This component has all of the files that are required for installing Tomcat and configuring it with the Apache Web server.

#### Disk Space

The available disk space for the installation directory specified is shown in the (Disk Space) Available field.

The disk space required to install the components selected is shown in the (Disk Space) Required field.
