Cannot run impedancefitter

[StefanPofahl]

I installed impedancefitter as follows:

Conda.pip_interop(true, Conda.ROOTENV)
Conda.pip("install", "impedancefitter==2.0.3")

If I give the command:

impfit = pyimport("impedancefitter")

I receive the error-message:

ERROR: PyError (PyImport_ImportModule

The Python ... and re-launch Julia.

) <class 'ImportError'>
ImportError('DLL load failed while importing _common: Die angegebene Prozedur wurde nicht gefunden.')

I have checked the python version, it is:

PyCall.pyversion
v"3.9.13"

Which should be sufficient. Any ideas?
