I can't figure this out on Windows 10.

1. I installed Python using Anaconda (e:\anaconda3)
2. Installed Vapoursynth (all users) (e:\vapoursynth)

python myscript.vpy works fine!

import vapoursynth as vs
from vapoursynth import core

print(core.version())
clip = core.std.BlankClip(format=vs.RGB24, color=[0, 0, 0])
clip.set_output()

vspipe and vsedit don't work.

vspipe --info myscript.vpy -

Setting PythonPath in registry to "e:\anaconda3" gives:

Failed to initialize VapourSynth environment

Setting PythonPath to "" gives:

Fatal Python error: initfsencoding: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'

Created a batch file clearing all environment variables except for path, systemdrive and systemroot.
No change, same problem.
