Hello,

I'm trying to execute Waveforms python examples  but i get the following error:

Traceback (most recent call last):
  File "C:\Program Files (x86)\Digilent\WaveFormsSDK\samples\py\AnalogInDigitalIn_Acquisition.py", line 17, in <module>
    dwf = cdll.dwf
  File "C:\Python37\lib\ctypes\__init__.py", line 426, in __getattr__
    dll = self._dlltype(name)
  File "C:\Python37\lib\ctypes\__init__.py", line 356, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: [WinError 126]: The specified module could not be found

Could you help me?

Thank you in advance.

Hi @RubenPadial

Make sure the WaveForms Runtime section is installed:
https://reference.digilentinc.com/software/waveforms/waveforms-3/start

The Microsoft Visual C++ 2008 Redistributable dependency should be installed by the WF setup.
You could try installing directly from:
