Where is the Vensim DLL file?

Post by QuinZ »

I am using Windows 10, 64 bit Vensim PLE, and 64-bit Python

I'm using the python Exploratory Modelling & Analysis workbench here: https://emaworkbench.readthedocs.io/en/ ... index.html

However, it cannot find the Vensim .dll files when I try importing the connector. I get the following error:
ImportError: vensim dll not found
When I go to the vensimDLLwrapper.py file, which generated the error, and the comment at the top says:
by default it is assumed the dll is readily available. If this generates an
VensimError, you have to find the location of the dll and either copy it to
C:\Windows\System32 and/or C:\Windows\SysWOW64, or use::

vensim = ctypes.windll.LoadLibrary('location of dll')

Typically, the dll can be found in ../AppData/Local/Vensim/vendll32.dll
I have looked in System32, SysWOW64, AppData/Local and AppData/Roaming/Vensim, and I can't find the vensim DLL anywhere.

Oh, that explains it.

Alright then, thank you very much.
