Topic: HELP PLS | MPC-HC: Unable to initialize VapourSynth API 4.0

Hi!

I installed SVP PRO 4 with MPC-HC player and RIFE AI component, and vapoursynth (VapourSynth-x64-R68.exe from https://github.com/vapoursynth/vapoursynth/releases), and Python 3.12.3

Checked VapourSynth filter to prefer in MPC-HC settings

My Environment Variables:

User and System variables:

PYTHONPATH C:\Program Files (x86)\SVP 4\mpv64

Inside Path:

C:\Program Files (x86)\SVP 4\mpv64
C:\Users\krisz\AppData\Local\Programs\VapourSynth\core
C:\Users\krisz\AppData\Local\Programs\VapourSynth\vsrepo
C:\Program Files\VapourSynth\core
C:\Program Files\VapourSynth\vsrepo

When is start mpc-hc i got "Unable to initialize VapourSynth API 4.0" and an other error (screenshot attached)
What should i do? About a month ago i had the same problem and i solved it but i reinstalled windows and i dont remember how to solve this again.

do not install "VapourSynth-x64-R68.exe from https://github.com/vapoursynth/vapoursynth/releases), and Python 3.12.3"
SVP has everything it needs.

You can use standalone MPC-HC with standalone VapourSynth, I tried use embedded MPC-HC and VapourSynth but it just didn't work for me
