Installing PTC Windchill Patches
* 
You can skip this if you already installed the Windchill Patches.
The required PTC Windchill patch adds several web service endpoints that allow ThingWorx to interact with Windchill. The name of the ZIP file identifies the release in which it should be installed. For example, on a 11.0 M030 system, install the patch in 11.0-M030_WCTWXExtension_{version}.zip.
Each patch includes instructions specific to the release. To install the patch, unzip the file and use the instructions found in the Readme file included with the patch.
Check this topic for information about the supported Windchill versions and patches: Prerequisites for ThingWorx Navigate 1.7.1.

Make sure to reapply the patch after every update of Windchill CPS.
Now that you have the and the patches, it’s time to proceed to the next step: 3. Import ThingWorx Navigate Framework Extension Files.
