Libum not correctly installed/located on windows 10 pro?

[natecermak]

I am unable to run the test module or run UMP.get_ump(). Both present the error below:

PS C:\> python3 -m sensapex.test
Traceback (most recent call last):
  File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.12_3.12.1264.0_x64__qbz5n2kfra8p0\Lib\ctypes\__init__.py", line 450, in __getattr__
    dll = self._dlltype(name)
          ^^^^^^^^^^^^^^^^^^^

    self._handle = _dlopen(self._name, mode)
                   ^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: Could not find module 'libum' (or one of its dependencies). Try using the full path with constructor syntax.

libum.dll is present in Python312/site-packages/sensapex/, as is umpcli.exe. I am on python3.12, and have tried both local installs (pip install -e <local-path-to-cloned-repo>) and install from pypi (pip3 install sensapex). I am running Python 3.12.4, pip 24.1.1, sensapex-py==1.400.0.

Any advice would be greatly appreciated. Thanks!

sensapex.py attempts to load libum.dll from multiple locations sequentially; error handling of one of the steps does not work correctly: The ctypes.windll.libum raises AttributeError instead of expected OSError.

with contextlib.suppress(OSError):
  return ctypes.windll.libum

The behaviour was changed in recent Python release
One possible workaround, that should work on old and new Python versions:

with contextlib.suppress(OSError, AttributeError):
  return ctypes.windll.libum

Thanks for figuring this out, @jhuhtamaki! Fix is released.
