Hi there, Thank you for sending me that. I can definitely see that something isn't get set correctly for Python when running CAVE for some reason. But, you've already tried installing and uninstalling CAVE many times, so what I propose is a small "hack" that I think may work. If you go back to your environment variables and re-add PYTHONHOME in as a variable, but this time make it point here: C:\Users\scope\AppData\Roaming\UCAR Unidata\AWIPS CAVE\Python Then, stop CAVE, clear caveData, and restart it one more time -- does that make any difference? Let me know? --Shay Carter She/Her/Hers AWIPS Software Engineer NSF Unidata If you're interested, please feel free to fill out a survey about the support you receive: https://docs.google.com/forms/d/e/1FAIpQLSeDIkdk8qUMgq8ZdM4jhP-ubJPUOr-mJMQgxInwoAWoV5QcOw/viewform Ticket Details =================== Ticket ID: QLB-140418 Department: Support AWIPS Priority: Normal Status: Open =================== NOTE: All email exchanges with NSF Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
