I have downloaded and installed the latest paraview binary distribution, and tried to import paraview to an external (conda 3.7.4, Windows 10) python installation which fails with the error:

```
#osp: INITIALIZATION ERROR --> could not open module lib ospray_module_ispc:
      The specified module could not be found.

```

In my PYTHONPATH and PATH environment variables I have tried all manner of combinations with:

```
C:\Program Files\ParaView 5.8.0-Windows-Python3.7-msvc2015-64bit\bin\Lib\site-packages\paraview
C:\Program Files\ParaView 5.8.0-Windows-Python3.7-msvc2015-64bit\bin\Lib\site-packages
C:\Program Files\ParaView 5.8.0-Windows-Python3.7-msvc2015-64bit\bin\Lib
C:\Program Files\ParaView 5.8.0-Windows-Python3.7-msvc2015-64bit\bin

```

none of which seem to help (the last includes the ospray\_module\_ispc.dll so should be possible to find). I have googled the issue which seems to happen from time to time but I have yet to see a resolution for it.
