Hi Grant, > ImportError: DLL load failed: %1 is not a valid Win32 application.
I've seen such an error when a 32-bit Python application tried to load a 64-bit DLL (or vice versa). I would run the Process Monitor (https://docs.microsoft.com/en-us/sysinternals/downloads/procmon) on the failing system to check which DLLs the Python application is actually loading and then check if it might be 32/64 bit conflict.
