The Modeler License Does Not Work after Upgrading Modeler
If you are upgrading Modeler, you will require upgrade or replacement Modeler licenses. For more information, see the Modeler Release Notes.
If you have a maintenance agreement with PTC, you should receive an email that provides instructions for obtaining the upgrade and replacement Modeler licenses.
If you are investigating problems with a floating license, the log file on the server may contain useful information. If you have installed Modeler to the default locations, the log file resides in the following location.
For 64-bit versions of Windows:
C:\Program Files (x86)\PTC Integrity Modeler\License Manager
