Preparing to Upgrade a Client Only Installation
* 
Only Windows Administrators who are also Modeler Administrators can perform Modeler upgrades.
For information about upgrading a previous version of Modeler, see the Upgrading Modeler.
If you have installed Modeler to the default location, the Release Notes reside in the following location.
For 64-bit versions of Windows:
C:\Program Files (x86)\Windchill Modeler\Modeler\System\PrintableDocs
For 32-bit versions of Windows:
C:\Program Files\Windchill Modeler\Modeler\System\PrintableDocs
Important: Before you upgrade a Client Only installation, ensure that you have obtained the appropriate replacement licenses from PTC. After upgrading Modeler, you must start License Manager and replace the license file on the server.
