@goanpeca, try printing print(libswmm) and see if that path points to the real DLL

[goanpeca]

@bemcdonnell yep it does point to the real one.

('c:/users/builder/pyswmm/pyswmm/swmmLinkedLibs/Windows/swmm5.dll', 'isfile:', True)

Does it work for you with the anaconda python?

How was this dll compiled (compiler toolchain)? Does it have any dependent dlls that are expected on the system?
