VI Server terminating VI

[alecjcook]

Hi. I am trying to load a vi from Python. (the .vi will build a specific executable).

To do this I have used the below python code. The VI Server seems to be terminating my attempts to open a vi. is there anyway of stopping this?

C:\> pip install pypiwin32
C:\> py
>>> import win32com.client
>>> LabVIEW = win32com.client.Dispatch("Labview.Application")
>>> VI = LabVIEW.getvireference('<path_to_vi>')
>>> VI.Call()

File "C:\...Python\Python36-32\lib\site-packages\win32com\client\dynamic.yp", line 516, in __getattr__  ret = self.oleobj_.Invoke(retEntry.dispid,0,invoke_type,1)
pywinterypes.com_error: (-2147352567, 'Exception occured.', (5010, 'LabVIEW', 'LabVIEW : VI execution terminated by the server.', None, 0, 0) None)

First guess is that VI has some output(s) connected (if all inputs are not set to "required") and you need to call it with 

vi.Call(paramNames,paramVals)

Thanks, but this VI has no inputs or outputs.
