Ensure that the installation properties use the same version of Java that is provided on the UI.
Set the appropriate permission levels to complete installation
Set the installation directory on Windows to ensure that the server can run as a Window service
Select an appropriate staging directory
Disable security features that may prevent the PSI from properly installing all solutions or optional products
Configure Windchill for Arbortext PE
