      Product: Ansys ModelCenter & ModelCenter Remote Execution 14.5

      Severity: Informational

      Introduction: Support for Python 2 is no longer available in ModelCenter 14.5. User provided 64-bit
      versions of Python 3 are supported.

      Issue: Python 2 will no longer be included with the ModelCenter and ModelCenter Remote
      Execution installers and Python 2 is no longer supported. Support for user provided 64-bit versions of
      Python 3 was introduced in ModelCenter 13.5 and remains available.
      Phoenix Integration software support 64-bit CPython and Anaconda Python version 3.5. Other variants
      of Python may work but are not officially supported or tested.

      Impact: Python 2 is no longer supported.

      Resolution: Users should update any Python 2 scripts to Python 3. Users who wish to use Python
      with ModelCenter can install a user provided 64-bit version of Python 3 and configure ModelCenter
      Remote Execution to use this version.
      Refer to the ModelCenter Remote Execution Help File for instructions on configuring ModelCenter
      Remote Execution to use the desired 64-bit version of Python 3. On the main page of the ModelCenter
      Remote Execution help file select the “Python Installation” link in the Quick Links section for more
