Issue Details

When I try to use Python Step Types for TestStand I get a popup saying NI Python Host has stopped working. In the problem details, I see:
Problem signature:
  Problem Event Name:    APPCRASH
  Application Name:    niPythonHost.exe
  Exception Code:    40000015


Exception 40000015 is passed through by windows, it points to an unhandled runtime exception. Generally, this is caused by either a corrupt install of Python or the use of an unsupported distribution (such as Anaconda).

To fix this ensure you have downloaded the official 2.7 or 3.6 release of Python from . If you are already using the official release of Python, then uninstall and reinstall to ensure your installation is not corrupt.
