Tecnomatix Oracle version is not suitable for eMServer

Trying to install Process Simulate Standalone and getting Oracle errors

During the install, if the only thing you need to install is Process Simulate Standalone, you do not need to install Oracle.  
Something that is missed often is at the top of the list, Process Designer is left active (No X) by accident and the Custom Setup will then install Process Designer and everything necessary for it to work.  Including Oracle.
Make sure Process Designer is not active.
