Pre-installation Notes
Before beginning installation of Windchill ESI note the following:
From 11 0 release onwards, SAP adapter is Java based, so there is no need for RFCSDK.
You may be asked to replace the <version>.xml file that already exists in the folder. There is no danger in doing so and you can continue with the installation.
If you are installing both a TIBCO Adapter for an SAP system, and a TIBCO Adapter for an Oracle system, then you must install both adapters in the same location. If you have an adapter installed already, and you would like to install the other adapter in a different location you must first uninstall the first adapter and the TIBCO Runtime Agent.
From Windchill 10.2 M10 onwards SAP JCO 3.0.8 or higher 3.0.x is supported. SAP JCO 2.1.x is retired.
On Windows, if you already have an older librfc32.dll in the %WINDir%\system32 directory, replace it with the one that comes with JCO.
From Windchill 10.2 M30 onwards, all TIBCO components including, TIBCO SAP Adapter on Windows platforms, are 64bit application. SAPJCO must be of 64bit mode or flavour.
SAP JCo Libraries for Design-time: Download SAP JCO 3.0.8 or higher 3.0.x from the SAP Service Marketplace.
From Windchill 11.0 M30 onwards, all TIBCO components including, TIBCO SAP Adapter on Windows platforms, are 64 bit application. SAPJCO must be of 64 bit mode or flavour.

This section describes the steps that must be completed before you install Windchill ESI using the Middleware Installation and Configuration Utility.
To prepare your system for the installation of Windchill ESI use the following procedure:

2. Copy the contents of the Windchill ESI Integration Suite for <platform> CD, and the Windchill ESI Adapter for ERP CD, to this staging directory, where <platform> represents the operating system you are using.
